BMG anti backlash system

thingiverse

It's a straightforward replacement for BMG extruders' pneufit. You'll require an M4 nut and a 2mm drill bit. To accomplish this: 1. Once you've installed the nut, screw in the bowden into the adapter without exceeding the nut or as shown in the picture (for better filament guidance once installed). 2. Drill the bowden end to the length of the part, then test that the filament slides correctly inside. 3. If you prefer to go over the nut, you'll need to unscrew the bowden to place the part and screw it back in its position, which will guide the bowden into the extruder housing.
