fischertechnik screw snail with gear

thingiverse

I have designed a fischertechnik srew from one piece. At 0.1 mm resolution, the game is the same as the original. At 0.2mm it is a little heavily because there is almost no game. So that it can be printed without raft I have added a 20 gear. Inside is a 4mm fischertechnik shaft. Without this, the screw is not stable. The transition between the gear wheel and the screw is a fracture point. Caution when removing the pressure bed. I have printed the snail up to 30cm. From 25 cm it became somewhat unclean by the movement of the nozzle. A printer with a firm print bed is recommended. The snail I have produced in the 30 mm grid. I have removed 3.5mm for a spacer ring. The should be on the gear side so that this can run freely. Grid size: 120 160 200 240 300 Feedback and change requests are welcome.
