As if Prusa printers aren't already mesmerising enough to watch. By adding a Motor Rotation Indicator, you've got no reason to spend countless more hours watching it turn! Oh, well, that's what I do anyway! Love em!

Here's my Hourglass inspired design and if you print it in the Prusa orange it looks amazing and really does complement the printer. It takes a few minutes to print and stops automatically at 92% for you to insert your 8mm x 3mm magnets and then it continues to close off the design. For full effectiveness, place one 8mm x 3mm magnet on the motor spindle and then just attach your hourglass for the perfect finish.

I've included the gcode and stl files, as well as some photos during printing and the finished part. If you have a Prusa i3 Mk3S, then you can go straight for the gcode file.

Happy printing and happy mesmerising.

Print instructions

I would suggest that you clean the bed for adhesion and print with standard Prusa Slicer PLA settings for your PLA and colour.
