It's not pretty but it gets the job done. 

I encourage you to buy Elecrow's official case for this device. If you have ended up with the bare board though, this model is better than nothing. Something thrown together to protect my test device.

Additional Hardware

• 8x brass threaded inserts (M2 x 4mm x 3.5mm or similar)
• 8x screws (M2 x ~5mm)

Printing

Front case should be printed with flat edge on bed

Post Processing

Threaded inserts should be pressed into the case using a soldering iron set to a low heat.

The four screw holes in the sides of the front case may require additional drilling to correctly align with the threaded inserts.
