Side mount spool holder
thingiverse
This is a ultra simple spool holder that takes advantage of the 50-55mm hole diameter of most filament brands. The spool holder provide a super smooth filament delivery without the use of bearings. I recommend printed with 3 perimeters and adjust setting so that infill overlap is 15% so that the infill will be structural. 2020 extrusion nuts: https://www.amazon.com/PZRT-50-Pack-Nickel-plated-Aluminum-Accessories/dp/B076DWF76L/ref=sr_1_1_sspa?s=hi&ie=UTF8&qid=1539851010&sr=1-1-spons&keywords=PZRT+2020+Series+50-Pack&psc=1 Assortment of M4 bolts: https://www.amazon.com/cSeao-Phillips-Machine-Assortment-Stainless/dp/B07D69XXFB/ref=sr_1_2_sspa?s=hi&ie=UTF8&qid=1539850967&sr=1-2-spons&keywords=cSeao+m4&psc=1
