Extra parts for Motorized Marble Machine.

thingiverse

The motor block and spiral catch are two additions for enhancing a motorized marble machine. The motor block provides clearance if a small grub screw is unavailable, while the spiral catch offers a neat finish at the bottom of the spiral. Print the spiral catch carefully using fan support for easier removal, as it's quite tiny. Test results on its effectiveness are awaited, so feel free to try it out and share your findings!
