Parametric hourglass motor activity visualizer

Created the parametric model from scratch, inspired by the model linked in the “remix” section.

The model fits the X-axis (and extruder probably too) motors of Prusa MINI+ nicely, by providing the cylinder of 8.8mm in diameter. I used two 6x2 magnets stacked atop each other (4mm) with additional 1mm of clearance for motor's shaft. The inner diameter is 6.1mm.

Printed on my MINI+ with PLA+ filament, on slightly lower temperatures (first layer 210, other layer 200) to allow for more stable bridges.

No supports were needed, just both inner and outer brims for the “sand” to hold firmly.

You can print with the combination of colors to achieve beautiful results.

My model is inspired by this model, but created completely from scratch. The main difference would be the 5mm high hollow cylinder for inserting two 6x2 magnets.
