John 3:16 RBS rev d Rolling Ball Sculpture Marble Run

thingiverse

I revised the John 3:16 RBS rev c design to include extra bracing, ensuring it doesn't require support when 3D printed. Additionally, I removed a problematic brace from that revision. The marbles and track will likely need gentle sanding to prevent them from bouncing off the track. To identify bumps that need to be sanded, try rolling the marble between your fingers or running your finger over the track. You can view my YouTube video at https://www.youtube.com/watch?v=G3nHviwY5G4 for more information. The original design is available on Thingiverse at http://www.thingiverse.com/thing:64764. It took me approximately 5 hours to print, and I used a raft but no supports during the printing process. I've developed an improved version of this design, featuring a shallower track that seems to work better. The marbles on this version are slightly smaller, allowing them to ride lower within the track, which helps keep them on course.

Print Settings: Printer: Geetech MeCreator2 Rafts: Yes Supports: No Resolution: 0.2mm Infill: 15% Post-Printing Instructions: Gently sand the marbles and track to remove bumps that might cause the marble to bounce off the track. Design Process: I scripted the original track using a custom script, then imported it into Tinkercad and added additional bracing to avoid needing supports during printing.
