Mobius Track Fidget

I created this mobius with track to hold a small ball.  The ball runs freely through the mobius track, from front to back and bottom to top.  The mobius has a 540 degree twist, so that if the ball starts at the front top of the mobius, after one full circle, it will be in the back top part of the track, and vice versa.  The ball requires two full rotations around the circle to return to the starting point!

 

To print, print the ball first.  Once that is done, start the mobius.  Near the halfway point, the print will pause.  

 

At this point, insert the ball into the track as shown.  It should freely fall to the bottom.  Once inserted, resume the print.  The ball is small enough that it can probably be pushed in after the print is done, but I didn't take any chances and inserted mid-print to be safe.  Depending on your printer and filament, this may be an important step.

 

WARNING: there are a lot of supports on this one.  Take them off carefully.  Worth the effort for the result in my opinion.

 

Enjoy!
