You are buying digital STL file available to download immediately after purchasing. You will need a 3D printer to print it. This module fits on all of our marble machines.
Marbles never seem to want to drop, fun trying to see how many can get on a level a one time. Easy print.

Great "Hang-time" for the marbles
Easy print and assembly. The marbles circle the funnels for an amazingly long time before dropping in. Works well in any position due to the long playability of the marbles.
