Marble run by dirtywolf Sep 17, 2012


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.

Ya, same here :)

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

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.

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).

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.

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!
