This is the spool mount that should have come with the printer! Clips on the bottom rail and points up to the feeder (check out the picture of my printer). Mount the spool arm that came with the printer to the end of this clip and the spool sits right next to the feeder. No Bends.. No friction points.. No extra hardware needed..

***Made it tight (so it wont ever vibrate) but with a clean print you can tap it up the rail 20mm (1 1/8") ONLY!! Youll want to tap it all the way up the rail.. dont.. or else the spool will want to hit the feeder stepper motor..

Ive included two of them (a shorter and longer one) the shorter one is a bit lower so the filament has to go up to the feeder from the spool and the longer one has the spool about perfect height but sticks out a tad more to the left. Your choice. but Longer is better :)

Looked briefly and didn't see the makers I used but this is a remix of sketches Ive combined about 3 different ones to get the best of features from each in one package. Found a sketch that had a longer arm but it needed extra screws so I took the rail clip from another so now no extra hardware is necessary. Made the holes for the nuts a little smaller so they line up with the holes perfectly. It looked kinda flimsy so added a little support going to the head of the clip. and stamped it with a .1mm "3" (testing my printer, looks cool so I left it for you)

To those who originally designed the works I've used thank you!
