Create an infinite loop of mini marbles that slide around a tiny rollercoaster!

The Mini Marble Run 001 is a collaboration project with MakerWorld to showcase the wondeful and infinite possibilities of the new Maker's Supply kit! This model features a motorized spiral lift that transports tiny steel balls upward to create an endless loop of marbles riding a rollercoaster.

The entire model is assembled using snap connectors, so no glue is needed at all and it will be simple to disassemble if you need to reuse any of the non-printed components.

Here are the non-printed components needed (all available in the Maker's Supply kit):

• 6mm Steel Balls (FA001)
• 1x Power Distribution Board (PDB)
• 1x On/Off Switch Board ()
• 1x Jumper Connector (IC006)
• 1x USB Power Cable (IC001) OR 1x AA Battery Case (IA003 or IA004)
• 1x Wire 20cm (IC007)
• 1x N20 Series Motor with Gearbox and Dual Axle 150rpm (LA009)

Everything has been tested on the X1C, A1, and A1 mini! All parts fit on the A1 mini bed.

Several pieces in the project use specific settings to ensure the model operates as smoothly as possible:

• Main Coaster - To make the path smoother, I've used adaptive layer height to minimize layer ‘steps’ along the rollercoaster path
• Spiral Lift - To make the lift smooth as well as avoid supports, this also uses adaptive layer heights

All of these specific settings are accounted for inside the provided profiles, so no need to do any of these changes yourself if you're using a Bambu Lab printer.

Adaptive layer heights makes a large portion of the model use 0.12 mm layer heights. This means that some filaments will not be optimal for a perfect rollercoaster path. However, I have tested the model with the standard 0.2 mm layer height and it still works well, just not as smooth of a path for the marbles to follow.
