Interesting idea!
If the early mirrors can use the existing holes the adapter would mostly be used to hide the extra holes.
I don't think a plastic adapter would be strong enough to hold a mirror on its own, it would be safer if the mirror bolts go through the door, but I'm all new to this so I might be wrong.
Just bought a Bambulab P1S and will have to learn how to use it!

AchtungKraft makes bullet mirrors with flag mirror mounts.

Yes, those are very nice products. I was hoping for something that would allow me to use the stock, 72/73 mirror.

Anyone out there find any gearshift knobs for a G50 transmission?

I can buy one for USD 150, but now that I bought my sewing machine, I am more inclined to print a knob out and then cover it with matching leather.

I'd love to be able to start from a known fitting knob.....so...anyone find one? I checked Thingverse already...no luck...

Thanks in advance!

PS - I am starting on one which is spherical, will get it done up and fitting and try to post to Thingverse. Fun part will be the insert with the numbers on it...should not be too bad

OK, answered my own question....shifter knobs are easy as per below. Insert is from our host, just in the process of getting ready to cover it in lambskin, but it looks OK just printed in ABS (100% infill and 5 outer layers for strength).








It bolts in using the standard method single 8mm. Turns out you can adjust the height of the ball a bit internally, I made mine a few cm shorter as I have arms like a monkey.

I tried 3 or 4 until I got the diameter and shape the way I wanted it, and I like the spherical shifter....but almost any shape is possible.

Here is the latest update on the console. It includes Autoheat/AC controls, alarm button, antenna up/down, PCCM box with dual USB as well as a 7 light warning system for low washer fluid, parking brake, oil cooler fan on etc.



I put in the orange lettering just for fun. Easy to do in Fusion 360, just do the text (Porsche font in available online) in a sketch, cut it all the way through the object you want the print on and then do another extrude to make the letters in a different colour. I put a 0.25mm backing plate on the letters which seemed to help them print on the Bambu.

Then snap the letters in, tap them into the object - plenty of friction to hold them in place.

the "dot" on the 3.4 was a pain as well as the inside of the "9".

Other than that....looks ok and everything works.

Just get the knob covered in leather and it will be perfect...

A small project: electric vacuum install. This was done using a UP28 vacuum pump. I wanted it close to the brake booster to eliminate clutter and long hoses, etc. I wanted to eliminate any fluctuation in the MAP signal due to brake usage.

I designed and printed a bracket that attaches to the back of the booster using some hex standoffs. The print uses PETG-CF which is plenty strong enough and heat resistant. I painted it with 3M undercoat for some texture.

So far, this has worked out great. I placed two check valves in line for redundancy (they are CHEAP) and it works great. It takes about 3 seconds to build initial vacuum and I only hear an occasional pulse in use.

Made a filter / intake cover for a 2.7 MFI intake and an air duct distributor for 50mm hose lines for a friends 914-6 with a 3.6.

Carbon fiber Nylon. The duct piece took more than a dozen tries to get right.

[Showdown]

Been using nylon/carbon, nylon/glass and some exotic German nylon mixes for high temp parts and am amazed at how strong and robust they are. Takes lots of fiddling with print settings and print orientation to get good results but man, it’s a cool material.

Im trying to have someone design a modification for my 930 tea tray whale tail, and he needs a "STEP file thats 1:1 ratio". Does anyone have a true scan of the tea tray? Desperately need. Will pay for service provided.

Could you please share the file for your air distributor replica?

If and when I finalize the design to a degree that I’m satisfied with I’ll be posting everything. I’m still working on it and will push ahead this winter now that driving season is winding up.

I spy AC/Heat ducting happening.

I might have several, as well. Winter "inside project" time is nearing so I will be back at it soon. Depending, I may have a completely new setup by spring.

[Showdown]

The printer has been very busy (with another project as well, shh) and as soon as I pull the CR unit and model the fresh air intake I’ll be able to start assembling.

All new servos, new design, new electronics, new code… etc.

That said, I have an engine and trans project that are the priority right now. Lots to do!!!

Bambu Labs just introduced a new filament PPA-CF that looks unreal- basically plastic metal. Also priced accordingly at $150 per kilo. I want.

This new material looks awesome. It might be just the ticket to enclose the PTC defrost heaters that I have been working with. ....new possibilities.

Also, samezy on the "new" things. I am switching gears on the servos, again. I found a couple new options to try this winter. I have the condenser modeled and ready to print. I have the frame from send-cut-send already and now it's just a matter of time to print, assemble, and test everything. It includes a fresh air valve which I am most excited about. I still have a few things to work out, but overall, I'm stoked for a new version.

Anyway, one fun one was replacing the hose from the auxiliary footwell blowers to the side vents. This is the state of my current ones and the size is not easily obtainable aftermarket and Porsche shows them as NLA.



The ends were badly frayed and really they were too short at best.

Anyway, printed these in TPU, took a bit of fiddling to figure out how to make the hose actually bend, easy once you think about it, but then the trick was to print it.

Bambu did very well although it prints vertically with no supports and the top gets pretty wiggly. The end printed last shows some stringing but it seals and is plenty strong.



...and here it is in position



I think the TPU will be fine temperature wise, it is rated to 85c, but worst case I just go back to the drawing board and either try a more heat resistant plastic (not that likely) or hit up the aircraft guys for the closest size I can get and live with it.

What was the trick to getting it to bend?

I drew this:

Have you created a finished product yet? Very interested in this considering there are not many aftermarket available(that actually fit properly).

It's definitely a cool time to be into 3D printing, even for people who are not such nerds who enjoy it as a hobby in itself (like me )... The new filaments are awesome and are going to make it much more accessible to home print technical parts, without having a 150°C chamber that is required for PEEK, PEKK, Ultem etc.

For your application with a PTC heater Joe I would also look into Bambu's PPS-CF, a bit less tough than PPA-CF and weaker layer adhesion in Z, but that you can design around that, and the 264°C heat deflection temp is impossible to beat on a non commercial printer.


Very much looking to see what you come up with next for improving the CR system Julian!
