Focuser Module MKII

Remix from https://www.thingiverse.com/thing:5140868 .Only difference is the opening for 12V external power.

This is the box I'm using for my focusers. They are based on Ardufocus (https://ardufocus.com/). This specific build uses:
- Arduino Uno
- "Driver" ULN2003
- Stepper motor 28BYJ-48
- 4x M4x12 screws with nuts
- 4x M2 screws for fixing boards to the box.

This is just the focuser box. Extra adapters will be needed for the different telescopes. I'm a lazy person so my designs have a few premises:
1. No modifications to the telescope.
2. Have to be easy to remove, in the dark, if it stops working.
