Arduino ProMicro Case

thingiverse

This is a straightforward Snap-Into-Place enclosure for the Arduino Pro Micro that shields it from scrapes, falls, and other forms of damage. The design consists of a single piece with interior dimensions of 37.21mm x 3.5mm and four holes measuring 18.6mm in diameter, along with outer dimensions of 38.53mm x 4.5mm x 20mm. To accommodate other boards like the Digistump, simply resize the design to fit. Once snapped into place, the Arduino will securely remain inside, provided that the print quality is good and the correct board is utilized. Interestingly, I found that printing without support material yields a slightly better fit, as the Arduino slides in more smoothly. However, once the board is enclosed, not all GPIO pins are accessible. Be aware that removing the Arduino from the case can be challenging; you might need to break the case to retrieve it safely. On average, the print time for this design takes about five minutes on medium quality settings.
