Marble track - rails (Gravitrax compatible)

I found a couple of rails here on thingiverse but wasn't satisfied with the performance results when building a track with it. Therefore I designed my own rails from scratch, including a 4 and 5 tile overspan. Check those YouTube movies for a demo: https://youtu.be/gLjz_M5uejk If you found this useful, please donate what you think it is worth to my paypal.me. Help cover the time of design. Thanks, Enjoy! Print Settings Printer Brand: Creality Printer: CR-10 Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 Infill: 80% Filament: REAL PLA Silver Notes: Use supports to print the rails. I use supports which are printed in 30 degrees angle to have maximum support surface to print on. Category: Playsets
