Features:

• Flexible buttons. Reset button indicated with inset circle:

• Strong enclosure for impacts and transport
• Snap-fitting lid
• No hardware for assembly (only for optional fan)
• Mounting provided for 30mm fan (ensure your fan isn't too thick)
• Mounting holes on bottom: 100mm*50mm M3
• Recessed USB ports for easy access
• Compatible for custom soldered headers (both male and female)
• Snap fit dev board in to place with secure hold (insert with ethernet port first. Bend enclosure on opposite side to not damage microusb port! The port sticks out and it can be broken off very easily)

I printed my enclosure with PETG-CF. PLA will most likely be fine too.

To reiterate:
Insert board with Ethernet port first. Careful not to break off the microusb port on the other side of the board. Bend the enclosure out of the way so the port isnt pushed upwards.
