Raspberry Pi 3 B+ compact case/enclosure

A compact 3 part modular case for Raspberry Pi Model 3 B+ with access to GPIO pins and with heatsinks exposed for better cooling. 
 

The circular recesses in the front plate and shell near the front are for 6x2 mm magnets, though it's a pretty tight fit anyways so they're not necessary.

In the future I'll try update this model with a HDMI cut out, feet or places for more 6x2 magnets.

Printing:

• front_plate.stl
  • no brim
  • no supports
• top_plate.stl
  • no brim
  • supports (if printing with overhangs for rail)
• shell.stl
  • print standing on the “rear” face (like in the picture)
  • big brim
  • supports for the usb port cut out
  • no support for jack cut out
