SpaceRail Lift kit

thingiverse

The parts are compatible with not a Lego 'one major brick/block manufacture' and the rails 1.75mm filament. The Lift doesn't require any printing support, printed vertically. The axles (215mm/50units) (x2) should be printed on the raft to ensure the dimensional accuracy. Pay attention with bed adhesion. The lift could secured with additional tape after the few cm printed. The rail clips require a bit of sanding to get jaws and ride just right. (e.g. sandpaper around 18650 battery as a jig)
