Marble Run based on Hilbert Curve

thingiverse

A marble machine designed around a third-order Hilbert Curve can be created and is optimized for printing on a Printrbot Simple Metal 3D printer. Watch the design in action here: https://youtu.be/y3rZ8ikVzTk Building Instructions Begin by printing all four components of the marble machine and then clean them up thoroughly. These parts can be printed without supports, making it easy to print each section separately. An update has been made to add a fifth wheel gear, which offers higher flow rates due to its extra holes and can replace wheel gear 4. Once your parts are complete, carefully drill out the screw and shaft holes to their specified sizes if necessary. Thread the hole for the set screw on the 12-tooth gear with a size 6-32 threading tool. To assemble this marble machine, you will need several specific parts: two screws to attach the motor mount, one screw to clamp the motor in place, and another 6-32 set screw to secure the 12-tooth gear to the motor. In some cases, it may be necessary to install a small screw and washer on the end of the shaft that drives the large gear.
