Printrbot Plus 2.1 Extruder Bearing Roller Clamp Holder...Thing
thingiverse
You know the little white plastic tube that lays horizontally across the wooden clamp atop the extruder assembly? It is what the clamp is rotating upon when you open it up by pulling up the fan to unjam your filament. Yeah, that thing. Anyways, I lost mine. Damned thing made a run for it and rolled away. This is a replacement based on measurements made with my calipers. I don't even know if it fits, yet. Yes - it is a tube. There's probably a "parametric tube" somewhere, but I didn't find it in 5 minutes so I made this. This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/9GH9NvO9r90 Instructions Guesstimated from observations and caliper measurements of openings into which the part is to fit.
