Marble Run Parts (JOYIN Compatible)

My kids got a Joyin Marble set for Christmas, and already want more pieces. It took a couple tries to get the fit snug, but it seems to vary piece to piece on the Joyin parts, so I'm not sure what the tolerance is.

I'm in process of printing the tribridge without supports.... we'll see how it goes. I designed the tribridge for better stability. A lot of the builds my kids have been doing are limited by the 4 inch sections.

I may post more parts as time allows.

EDIT: 12/30/24 - Added a revised V Slide part, the original had an error in it that didn't leave an exit for the marble.

EDIT2: 12/30/24 - Added Pipes part. One entry, six exits. Works great. I need to get pictures of the prints, but my kids are building at the moment. I made a 4 inch center to center to accompany the original (3").

EDIT3: 01/03/2025 - Added a bowl, two s curves, and three angled pipes with slots.

EDIT4: 01/05/2025 - Added slides and large spiral.

EDIT5: 01/07/25 - Added a single post with a half-tube spiral around it. I only supported from the bed and it works great!
