Case for Creality E3 Free-runs Motherboard (Ender-3/Ender-3 Neo/Ender-3s/Ender-3 Pro/Ender-3 V2/Ender-3 V2 Neo/Ender-5/Ender-5 Pro/CR-10)

I created this case for the Creality E3 Free-runs Motherboard (I believe that most Creality motherboards such as the 4.2.2, 4.2.7 so they should fit inside this case as well) because I wanted to use the motherboard to drive some stepper motors for a project. I'm using the board like an Arduino and wanted to protect it and be able to handle it without constantly touching the PCB.

I created it to be fastened without heat brass inserts as well, but I could add brass inert hole sizing if people want it. 

Printed on the MK4, generic PLA filament (hot pink because obviously)

• top_case: print with support (mainly for the 4 screw holes)
• bottom_case: print with no supports

20% infill

Needed:

• 6 x M3 x 4 (hold board in)
• 4 x M3 x 12 (hold power jack in)
• 4 x M3 x 8 (hold fan in)
• 4 x M4 x 12 (secure enclosure)

For power, I'm using:

• MEAN WELL Desktop Adapter
• PLDC-P1MS-SCT DC Adapter 2.5/5.5mm Socket -- Screw Terminals (https://shop.admtech.com.au/POWER-SOURCE-PLDC-P1MS-SCT-DC-Adapter)

But you could leave that out and feed the power cables through the same hole.
