I made a simpler version of LeeCarL's design to make it more approachable for people, while still giving you the tactile feel for the rim for sim racing.
I fixed a few things, added a way for the button guards to be secured and removed (if needed), removed the need for inset heat nuts, and took away the rotary buttons/shift-TC indicator/LCD screen. The end result, is a standard rim with 15 buttons (and the option to put in rotary dials on the faceplate if you want them).
The Porsche Logo is a design from tumes - https://www.thingiverse.com/thing:3814467
*I resized it to ~75% in Cura before printing (EXCEPT for height, keep that at 4mm to get colors correct). Print with the following color heights (the directions on his page are confusing):
0 - 2mm Gold
2.01 - 3.0mm Black
3.01 - 4mm Red
