I have extended the model of @HackerJack42 with a stepper motor (28BYJ48 with ULN2003). I got the idea to use this stepper motor from @Summons. For this I have redrawn the base so that all components can be installed and supplied by…
When I first received my Ender 3 v2, my wife sent me a link to the mechanical planetarium as a joke. But I actually tried to print it and became disappointed when I discovered that I could not manage tolerances well enough for the entire…

A laser collimator should be (perfectly) collimated at the factory. If this is not the case, it is (theoretically) possible to collimate it yourself. However, if this is not possible - as in my case, because I had no way of turning the…
This minor tweak edits the moon gear (now a step down/drive gear) and the finger wheel bracket to add a stepper motor and driver to the mechanical planetarium. I chose to do this in the PrusaSlicer as it allows for a bit of easy…
The standard EAF metal bracket doesn't fit the Baader Planetarium Diamond Steeltrack 2" focuser without modifying the metal bracket to fit the larger M6 screws so I made up this bracket which utilises two of the M4 “attachment screws” and…
