Summary

I loved seeing marble runs or any of those types of toys in store windows when I was a kid but I never owned one. I designed this (ongoing) set as a gift to my younger cousins this Christmas.

I'll be updating the files and adding as I go.

Enjoy!

UPDATE:
The new marbleRun-swirl works great and was a hit with my cousins! I just wish I could have printed more parts for them!

Instructions

I've printed these on my Afinia H-Series 3d printer with these settings:

0.25mm Resolution
Loose Fill
Normal Setting
30 Degree support

*The mill might have to be printed at a better resolution to be smoother so it turns more freely unless you're okay with filing/sanding it a little to get it to turn smoothly.

I designed this to work within my printers capacity. I doubt it will fit to existing marble runs since I didn't use them as a guide.

Uses 14mm marbles.

List of parts so far:

marbleRun-H - Marble slide.
marbleRun-I - Height extender with the top positive and bottom negative.
marbleRun-EndCatcher - Catches the marbles at the end.
marbleHopper - Makes it easy to load lots of marbles!
marbleRun-mill - Marbles go through and the mill turns! Attach one of the connectors to the side of the slide, put the mill in and then attach the other connector.
marbleRun-flipper -Marbles go through and the flipper turns!
marbleRun-2wayExtensions - 1 each of the Negative & Positive. Use this to extend the height, add a large gap, or create a custom piece.
marbleRun-2wayExtensionNegative
marbleRun-2wayExtensionPositive
marbleRun-Swirl
marbleRun-XLExtension - Extra Large extension that is the same height as the marbleRun-Swirl!
marbleRun-Curve
marbleRun-2waySplit - Splits the marbles in two directions.
marbleRun-Funnel - Big funnel to have marbles hop into!
marbleRUn-Chute - Can dispense marbles into the Funnel.

I will .zip all the files after I am finished finalizing the files.
