Parametric Mendel Extruder
thingiverse
René Pijning designed the SCAD Mendel Extruder, which I made parametric and added support-free points over horizontal holes. Adjustable parameters include bearing race diameter for the pinch mechanism, securing bolt size, and filament diameter. The bearing support hole is slightly oversized to accommodate different sizes of bearings, shafts, and filaments. Note that this design isn't compatible with 608 bearings due to clashing with M4 securing bolts; you might modify it if needed, but please share the updated version.
