HAL 9000 (v4)

Notice: I've moved this project to [printables.com](https://www.printables.com/model/218766), go there for newer versions.

This is an update to v3 of my HAL9000: https://www.thingiverse.com/thing:5266563

Major changes:
- added a replacable panel inlet for the top side in order to more easily upgrade/modify the electronics (not requiring to reprint the full top half enclosure for added controls; only one of the hal9000-part_enclosure-panel*.stl has to be printed and replaced in your assembled HAL)
- replaced turnbuckle locking mechanism with screws
- reworked the display frame component
