Gravitrax

SummaryHere are some models for the Gravitrax ball track. All the models can be printed without supports. I used 0.3 mm layer height and 10% infill.The funnel base can be used as a base for the Gravitrax small funnel.I've printed the funnel with 0.3 mm layer height, but afterwards I had to polish it with the sandpaper and the solvent. May be it would be propper to use 0.2 or 0.15 mm layer height.For the pendulun axis cut two pieces of filament or 2mm nail and just press them into the holes.The connector can simply be pressed into the appropriate slot. Glue it if necessary. However, for me it holds well without glue.Print the spacer upside down.
