Cetus 3D Extruder Drop Stopper v.2

v2.22: You need an M3 dish screw that's 8 mm long and an M3 screw that's 25 mm long to get started. By turning the 25 mm screw, you can fine-tune how far the fall slides. v2.23c: For v2.23c, you'll want two M3 screws that are 25 mm long to build it. This design has an even better slippage suppression effect than before. In v2.22, there was still some slippage at the bottom that wasn't fully fixed. v2.25: I've gone back to a simpler design for now. The subtle adjustment of slippage hasn't been perfected yet. If you don't have an M3 25 mm screw handy, you can substitute one that's 30 mm long instead. This version is definitely better than the last one. https://www.thingiverse.com/thing:3040756
