hyperpixel 4.0 screen for Prusa mk3s

There's a different project for Raspberry PI 4: https://www.thingiverse.com/thing:4197636
Do not use Pi 4 version of this panel, it's incomplete, I've designed it using rpi4 model and the real rpi4 doesn't fit!

Front panel for Prusa i3 mk3/s extended to accommodate hyperpixel 4.0, raspberry pi 3b+, and a buck converter.

I've been using waveshare 3.5" screen for over a month, it has some advantages like price, and using only 10 GPIO pins but hyperpixel is so much better. It's more resposive 60fps vs 5fps, better colors, and better touch sensor. The active sceen size is on the other hand only marginally bigger 50,8mm x 72,9mm waveshare vs 52mm x 86,2mm hyperpixel.

4 should be sufficient for one side.
