Title: plastic-parts for 3d-printing
Post by: mk24ever on February 09, 2022, 03:26:51 PM
for people who would not mind having 3d-printed spareparts in their cars,
i have made a list of links to freely available 3d-models, which i deem useful.

those i've even made myself:

fronstspeakergrid screwcap (sticking by magnet)
liner nut
headlight adjustment ancor (wrong threading, the screw will tend to stick, but it did for me)

the source code comes with them, but since i know the matter,
feel free to ask if you need some adaptions.

parts out of the thingiverse:

front emblem (https://www.thingiverse.com/thing:358536)
indicator cover (https://www.thingiverse.com/thing:4221964)
heater slider (https://www.thingiverse.com/thing:4759124)
heater speed knob (https://www.thingiverse.com/thing:4759119)
heater gear (https://www.thingiverse.com/thing:4759130)
sunvisor clip (https://www.thingiverse.com/thing:1603029)
window crank frame (https://www.thingiverse.com/thing:4233395)
internal door opener frame (https://www.thingiverse.com/thing:2246811)
external door handle frame (https://www.thingiverse.com/thing:4875327)
lock knob (https://www.thingiverse.com/thing:1655288)
seat knob (mk3) (https://www.thingiverse.com/thing:3027546)

engine lifter keeper (https://www.thingiverse.com/thing:1381119)
degreewheel for crankshaft (https://www.thingiverse.com/thing:4734576/files)

to be continued..
(regarding some stl files about clips and holders i do not find the corresponding thingiverse page anymore)

Really good link  :))

thank you :-)

recently i remade the stub on the back of the radio
which goes into a hole at the end of it's shaft.

does somebody know how to call it and this kind of shaft ?
such could help me with the description.

Radio location spigot, support spigot?
Title: Re: plastic-parts for 3d-printing
Post by: mk24ever on February 14, 2022, 12:56:56 PM
thank you, i will consider.

@Monkey i saw you did some blanks (https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=106.msg3684#msg3684)
for the switches in the window control panel :-)

since i've probably holed to much blanks (trailer light and stuff),
i think about redoing the blanks next to the radio.
however, this could be a nightmare in openscad.

finally my bolt for the radio:

carradio backsidestub (@PWardy sry 4 being ->stub<-born, but appreciate..)

to the admins:

what would you think about a subboard,
for instance 3D-Print under car parts or whatever is appropriate,
where one could roll out one mk2 plastic part per thread ?

thingiverse stuff:

differing golf ball gear knob (https://www.thingiverse.com/thing:4304024) (see here (https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=517.msg9091#msg9091) following this (https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=695.msg9044#msg9044), pic here, too (https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=118.0))

@Monkey i found caps like yours on thingiverse (https://www.thingiverse.com/thing:2424109),
but also liner nut's (https://www.thingiverse.com/thing:2768548), like mine (see threadstarter),
which do not have this additional bar on one side.

The plastic liner insets are still available new, it is a revised improved design so I have replaced all of mine.  Originals like these, https://www.thingiverse.com/thing:2768548, are in a bag in my attic.

Is this in your links?

No. 2A (191 501 159)

(https://volkswagen.7zap.com/ImgsWatermark/images//Bilder/070/070106000.png)

I was after some for a long time, before eventually turning up a pair.

When I saw them in the flesh thought they could've been printed very easily, saved me a lot of time!

Sods law, since found that someone has had the same idea.

Right, they're getting printed tonight then!
Plan to start my rear beam rebuild this weekend, so that was perfectly timed

Is that where the speed sensor goes

Certainly appears so, close enough to pick up that cage that usually goes on the back of the disc.

@L90E it's not in my links. i came across, but have not thought it would be needed.

i made a picture of my screwcap (first link of the thread):
(https://i.postimg.cc/jSW7cBs2/frontspeakergrid-screwcap.jpg)
unfortunately, the magnet shines through the black resin.

i tried painting the part, but this did not turn out that well
(too shiny and small bubbles on the frame).

is there a way for getting the surface right ?

I'd say this would be a good candidate for printing https://www.ebay.co.uk/itm/255098516896?hash=item3b650e75a0:g:rGYAAOSwmXVhHSfW

How about replacement side skirt clips?
I recall most of mine on the reverse side of the skirt are broken.
I can see the sill mounts (part number 191 853 913) are still available but from memory mine are all OK.
Not sure how durable the plastic used to create the parts is though but if there is a way to make them easily replacable that wouldn't matter.

edit:
Just found the replacement 'pattern' sill covers on VW Heritage not too expensive if I could extend the shopping list to £75 (edit2 to get free postage) but surely replacement clips would be cheaper.

@t2000, nice easy part, indeed. you could do it, i could do it (measures given). is there demand ?

@AndyBa, ah skirt clips, they are called. if cheap, i would have taken originals or replica.
but since there are so many parts on my mk2's which are 3d printed,
replacing them all would probably burn money, but there might be occasions.

recently i posted a picture about a printout of my radio support spigot (see reply 5, backsidestub).
it can be found here (https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=1326.msg9273#msg9273).

..and i also post it here:
(https://i.postimg.cc/4N4BN2Bx/blaupunktsc202interiorwithspigot.jpg)

the radio support holes of you gti guys, are they all made out of metal ?

for them, the standard measures are a bit big, so i have adapted them (standard is standard in my code).
Code: [Select]
// diameter while z=max, if there were no rounding:
dia_top=12;  // standard/plastichole: 13   metalhole: 12
// diameter while z=0,   if there were no basering:
dia_bot=13;  // standard/plastichole: 14.5 metalhole: 13

@AndyBa i got it wrong in reply 14.
i thought you have ment my screwcaps in reply 13
and you posted the link cause of the pattern
(although i was a bit puzzled
about how i was considered to extract it).

how does the part look like from the back side ?
if you have a detached one, may you post a picture ?

there are libraries out there, with which
one should be able to model the front side shape.
probably round anything or a bezier curve library.
i'm new to this, but i plan to go there anyway.

does the part only come with big bumper cars ?
we don't have those, so i do not have a specimen
and would need a pack of measurements.

regarding the structure, the part could probably be reworked after printing.

@Eddypeck you fixed your bumpers (https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=118.msg5684#msg5684).
Have you done something about structure ? How well did it come out ?
May you maybe put a high-res-pic of the restorated part into your thread (https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=118) ?

another possibility would be a heightmap.
there i would need e.g. a greyscale image,
where the color intensity represents the height.

i tried to scan the screwcapfront covered in chalkwater,
but it did not fade well plus i have a scanner issue.
maybe it does not like linux anymore or the other way.

I don't know if this will get any response, as the thread hasn't had much attention for a while it seems I just wanted to ask out of interest if one of the people with a 3D printer is willing to 3D print parts for other users upon request, I would imagine a fee would be included? If this is something that someone would be willing to do, what would the rough cost be?
Title: Re: plastic-parts for 3d-printing
Post by: mk24ever on May 16, 2023, 07:26:15 AM
@Tobyha01:
cause of delivery and stuff it needs to be someone located in england, right ?
have you already checked the prices of 3d-printing-companies ?


in general:
mainly on Lord_Vader (https://www.thingiverse.com/Lord_Vader)'s thingiverse,
i found a trove of parts, which i missed before.

also there are many parts i have not much knowledge about.
the abs-sensor-hole-cap from above is a good example, here.


many people prefer more oem-looking parts from ebay.
although there are also custom parts,
one could ask if covering 3d-models is the way to go.
to me, on the other hand, 3d-printing would math early vw-philosophy
of having a car, which is easy to maintain
and on which much could be quickly and independently done by one self.


if we like do to stuff there, vetting parts could help.

as opposed to the parts-quiz (https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=942), where one is supposed to know the part,
i've long considered a what is this thread, which maybe also could be used for 3d-models,
but there is also the further discussion if the part is relevant enough and stuff.
so i wouldn't be sure if there or here or what.


then there could be put effort into structuring the 3d-part-list better
like for example dividing the collection into different sections
like engine compartment, passenger cabin
and further into dashboard, ceiling or something.

without much consideration,
i would have my thoughts near a wordpress for this,
and maybe the library section.


another point is, that users from the web probably do not register
to actively ask for a model (and there are parts, mostly mine,
which are shared on that base).

some may even not peak english fluent enough to participate in this way.
many just want to quickly print something for their mk2.

course of fewer downloads, this probably wouldn't hamper
the forum-bandwidth as much as pictures.


i just wanted to express my thoughts, it doesn't have to be it or here, of course.

Wow that was a very deep and philosophical reply!

I haven't checked the price of printing companies, but I imagine unless I was getting something big or many things printed, then the cost would probably be disproportionately high relative to the item being printed. A good analogy for this is, it's like buying a £2.00 item but then having to pay an £8.00 deliver fee, where the  delivery fee represents the cost one might be charged by a private company.

I'm happy to pay whatever the cost is to a private individual specifically from this forum., as I'll know it would be the raw cost and maybe with a bit extra for their time.

To be honest I just wanted to see if it was something that people with 3d printers from this forum would be happy doing, and whether they would want to charge me a cost on top of what the delivery is, and a rough guide price. I understand that maybe it would only be available in the UK which is fine for me as I'm UK based.

To be honest for small things like clips, blanking plugs such as those used for switches in the centre console, are at least to me small things so it wouldn't bother me if they're not OEM as it's only plastic. I understand maybe to others it might be a bigger deal, which is fine but to me plastic is plastic.

I know @Monkey has some 3D printing.
Title: Re: plastic-parts for 3d-printing
Post by: Monkey on May 22, 2023, 01:52:34 PM
Yeah, I do dabble with the printing.
Was there anything in particular/any STLs you had in mind?
If it's just a case of printing an STL, it's easy, but to design something from scratch is much harder.
I'm no a designer by trade, so it takes me much longer. I recently designed a surround to allow fitment of an 02J shifter in the standard centre console and get the gearshift gaiter back down. Took me literally weeks and about 18 different variants until I was happy.

I'm currently working my way through a Fusion360 course, so far following the tutorials I've designed a few things - but that is just literally copying each step of what they are doing. I'm a fair way off creating my own designs, but that's a place I'd like to get to soon  8)
