Pi1541 Case

I remixed this to:
- support buttons on the top of the case
- a larger LCD
- stronger supports
- a custom PCB for buttons, which can be found here: https://github.com/ogg1e/pi1541-case-daughter-board

You can heat set 2mm nuts in PLA, but when I tried to heat set them in wood PLA, they wouldn't stick, so I had to glue them in place after heat setting them.
