Water Mill Marble Run

Water Mill Marble Run – Rollercoaster-Inspired Fun

This 3D printable marble run brings the charm of a water mill to life, using 8mm steel marbles and a hand-operated crank to transport the marbles to the top of the track. Crafted with a combination of wood and steel textures, the design blends rustic elegance with industrial style.

Assembling the gears and tracks is an engaging hands-on experience, allowing you to bring the intricate mechanical system to life. Each piece sticks together, to get a smooth track. Whether you're a fan of engineering or just looking for a creative project, this marble run is a fun and rewarding build.

- Every track has a small number printed on top in the middle, where the to rails connect. Check the end of the video to see it‘s positions. - Try to stick every track completely into the connectors. - You can turn the tracks inside the connecters some degrees, to adjust and tweak the tracks quite a bit if the marble doesn‘t run smoothly, falls out the track, stops or crashes other rails. - Glue: the bearings / the handle stopper / the buildings to the base (after assembly) - You need 8mm diameter Steelballs

Motorized Version

Also attached is the PrintProfile with all the necessary parts for the motorized version. The Assembly Guide first walks you through building the manual version and then shows you how to easily convert it into the motorized version in just a few steps.

You’ll need a few additional maker’s supply parts for this:

- N20 Motor (150 RPM) - Power Distribution Board - Button Switch You need to glue the big wooden parts of the motorhouse to the motorholder, if you want it to be stable to transport the marble run.

Aside from these components and the 3D-printed parts, no other materials are required—no screws, extra cables, or soldering needed.
