Wall-Mounted Arduino Uno Case with Magnet-Held Lid and Sliding Base

Case inspired by Thingiverse user ggoss and Thingiverse user modelatolyesi. References were taken from the former for Arduino Uno and fan dimensions and measurements, the latter inspired the wall-mounting legs with slots for screws. 

This model has slots for 6,35mm diameter ball bearings and 5,00mm diameter cylindrical magnets which are slightly loose. The magnets used for testing are typically used for articulated figurine or miniature joints. While they hold by themselves, I do recommend using a bit of glue even if the slots are tightened as the magnets tend to violently snap to any magnetic surface. The grooves where the sliding base fits may also be slightly adjusted depending on the printer and printing parameters. 

This case has a comb to sort jumper cables and supports a 4,00cm fan.

The table below shows a few relevant printing parameters used in a Creality Ender-3 Pro printer.
