Ferdinand Porsche didn't like the cars in existence at the time so he built his own.

We haven't built our own cars on our printers yet, but we can make replacement parts.

Example:

The Porsche 944 and 968 have a HVAC control that is mounted to the dash by an acrylic plate that snaps on the housing of the assy. 

Wonderful 30 plus years ago, but now most have the acrylic crumbling, the mount holes no longer hold. Some ends snap off, others the screw pulls through and then the Heater/Air Conditioning control assembly dangles from the dash.

There is a picture in this gallery that shows an original one with crumbling mount ends.

This file enables you to print a replacement. 

Use PET-G preferably clear to let the dash lighting to transfer through the mount plate and to around the controls. Transfer the lables from the old part and snap on the assembly to the housing. You do have to loosen control nuts on the rotary switch and potientiometer and to transfer switches but upon completion it will mount tightly to the dash again and put the factory bezel over it and the knobs and it's as good as new.

NOTE: THERE NOW IS A VENDOR SELLING A ACRYLIC REPLACEMENT on EBAY for $70 and the prices of these complete replacement control units have skyrocketed (even with broken disintegrating mount plates on them)

When I originally set out to design this replacement this part was unobtainable, however I now see that a molded replacement exists but you can print you own for a fraction of the price, 

Enjoy… step file included for you to modify or improve on.
