Description
There are tons of different BMCU versions to be found and download on the internet. But not all will/ might fit the parts you'll have in your kit. So not all designs will be suitable. So it will be very easy to waste time and filament by downloading and printing the wrong one.
This is the printable case for a BMCU 370C kit from Aliexpress, which has the 2 microswitches on the hall sensor board.
Boost MeBoosts are always appreciated :)
This print is for when your kit looks like the photos beneath and/ or has the described/ showed components:
The following manual does not describes the very same kit and/ or printout, but it's usable for about 80%. The remaining 20% will be not that very hard to find out, or I will go to update this description to point out everything in the near future.

PS:
My parts kit included the wrong chamber sensor (microswitches) springs (for this kit). I had to order new ones and now it works flawlessly and without problems!
Best is when the springs fall around the sensor pins (smaller part) but do not obstruct the hole for free movement. The length of 5mm is just perfect as it seems.
I had ordered the 5mm x 5mm (0.04mm) for this kit here:
