I designed this 3D printable box to fit Karl's Sim BOB, complete with a lid. The box features a hole for the outbound and inbound wires, one for the USB, and another for the 5V plug. It also includes the ability to mount it to a surface.

Box's dimensions:
Length: 218.18mm or 8.59 Inches
Width: 164.082 or 6.46 Inches
Height: 60mm or 2.36 Inches

To secure the BOB board to the 3D-printed part, you will need four M4 brass inserts. The size of the M4 brass inserts is 4mm in length and 6mm in outer diameter (OD).
