Gridfinity Marble Run Expansion 6: Looping Set

This is my attempt to design a looping for the Gridfinity Mable Run system. The first version didn't work so well, so I modified everything and now it worked!You'll also need the drop for marbles to gain enough speed!The drop is exactly 7 regular spacers high.I also designed the drop before the looping, but it was also designed before modification.ATTN: I would not recommend using any filaments that have a tendency to swell or have poor layer adhesion like silks or dual extrusion. I had almost ZERO issues using PLA, PETG & ABS, but when C7 Modeling tried a dual extrusion PLA from another brand, he did have an issue with the tabs on the bridge pieces getting stuck and breaking off. Maybe just try printing a couple test pieces with your filament of choice first.ATTN!! This is an expansion set. You will need the core set and some of the many other sets available in order for these pieces to be useful.Core Set: https://makerworld.com/en/models/645420-gridfinity-marble-run-core-set#
