First step, 3D print the parts: https://www.thingiverse.com/thing:3145193 I used TPU (flexible)
Epoxy doesn’t stick to mylar so you can use like a potato chip pack between the parts and your clamps. The epoxy wil goo through the TPU, making it very strong.
Wait at least 24h. 48h is better.
Step 5, griptape. I used a paper template I created by bending the paper around the board. Then you use a pen on the bendings.
There you go! Feel free to ask questions!
