Zero Clearance Extruder Body, No Coupling
thingiverse
Extruder housing with the following features: * Low clearance between the gears and the body opening, suitable for flexible filament. * Short path length before the filament enters the teflon tube. * No obstructions on the path, so easy to load filament - no edges to get stuck in. * Teflon tube is just a friction fit, with a open slot so you can see the tube's position. Probably only suitable for direct drive. * Nice thumb rest for squeezing the lever arm. Notes: * This is a drop in replacement for the extruder body, but you still need a lever arm, gears, etc.. * I've printed quite a lot with this, and no problems. Quite happy with it. * I've printed PLA, PETG, and 91A TPU.
