Made a extruder from 5mm POM today. It fits directly onto Nema 17 motors with 31mm hole distance
Parts were cut by a cnc machine, but should also be possible to make by hand if no cnc available.
Total cost less than 10 € and seems to work good.
Will replace the screw to adjust spring tension by a piece of M3 threaded rod with a self locking nut because the screw turns to easy.

Interesting design. Why not post it to Youmagine.com?
This kind of design already is on youmagine https://www.youmagine.com/designs/alternative-um2-feeder-version-two
Thats what this POM Version is based on.
Isnt YouMagine only for 3d printable stuff ? Because this needs a cnc milling machine to be made.
Hmmm…I don’t think they’d mind,but I guess you’re right.
I uploaded the files to GrabCad.com . Think this is the right place. https://grabcad.com/library/simple-extruder-feeder-for-3d-printer-5mm-pom-1
