Sturdystruder

A direct drive NEMA17, bowden, mk8 extruder design that attaches to 15by15 openbeam.
I've had some issues with existing extruder designs, namely that the pushfitting have been pushed through the plastic threads or come out of alignment, causing the filament to jam. Or simply that there was not enough pressure on the idler.
This desing attempts to fix those issues by clamping the pushfitting to an m5 nut and using leveraged tension on the idler.
I also wanted to be able to adjust the idler
