Big building block marble run set

Build marble runs FAST!

This set of marble run blocks is compatible with Duplo and compatible building blocks. Make large marble runs quickly! The ramps are all designed with the height of large building blocks in mind, making it easy even for young kids to build cool marble runs!

This run is compatible with most standard glass marbles.

Minimal supports

When printing, I would recommend a brim as the pieces have a small contact patch on the build plate. The 90 degree ramps require supports as does the funnel (but only under the opening).

Hints:

While it should be easy to figure out, the ramp pieces (90 degree and straight) both drop by an elevation of 1/2 the height of a full Duplo block. A little bit of experimentation and you'll get the hang of it quickly.

Use the funnels as a starting point... or try to shoot marbles off ramps into them!

See what you can do with the crossover pieces - have a friend or family member drop marbles at a different starting point than you and see if they collide at these intersections!

Need a ramp to go over another ramp piece? See if you can make use of the bridge support to allow marbles to criss-cross at different levels!

Caution - Adult supervision recommended:

Please make sure that if you print this for children that they are past the stage of chewing on their toys and that they have adult supervision when playing with these; 3D-printed parts can fracture into small, sharp pieces.
