Marble Maze With Interchangable Mazes

I created this as a challenge for our Discord server. The idea is to print the base and then exchange the mazes with your friends. I've included an easy one that I used for testing.

This design should work with a ~1/4" ball bearing as a marble and is printable on most smaller printers. I've included the source files so that you can scale the base to your needs. There is a step file for a blank maze that you can edit in your favorite CAD software.

Please post your mazes!
