A set of marble run pieces.

My 4 year old son has grown fond of marble runs recently, so we purchased a "deluxe marble run" set. I figured I could make this a "mega deluxe marble run" set by adding custom pieces.


Print out as many as you want, connect, add standard (~16mm) marbles and have fun!

All parts are 60mm high, and have print length of 120mm (so that it will fit on my up plus).

Currently a straight piece, a curve (left) and a riser.

I will add more pieces in the future.

If people want, I can also upload the Alibre files (.ad_prt).

I have printed some tests, but they are not compatible with the pieces that I have, "galt" pieces.

Did you end up having to add support material to print? I think if you made the underside arch up, it could be printed without support material. The pieces may wedge together though, I guess

The Up! software automatically adds support material, although I tried to minimise it. The only support material that is absolutely required would be under the "upper" end because there's a 100% overhang.

I think I wound up having support material under the main track, just to make sure it didn't warp too much. With more time I would probably try to find a way to get rid of this requirement.

Cool, i'm going to try printing one of the tubes I based off your design tonight. I'm pretty noob, and tall parts are tough for me.

Woot! we should make an open source marble run!

I'm obsessed. I've made like 20 parts since I saw this 9 days ago.

Oh man, if I was still a child.

You don't have to :) I'm having almost as much fun as my son putting all this together!

Ya, same here :)
