Universal Spool Holder for Prusa i3 MK2S, yes another one...

thingiverse

Lots of these to go around, here's my take. ### Features ### * Low friction design (bearings) makes it easy to get started * Most spools are compatible with this system * No adjustments are needed between different spool widths * Rollers for 90 mm, 100 mm and 120 mm maximum spool widths are included as standard * A curved flange prevents the spool from falling off during use * Easy assembly is a breeze thanks to the design * Bearing axles are reinforced with metal for added strength ### Non-printable parts ### * Four standard 608Z bearings are required, along with four M3x16 machine screws * Longer screws will work too, but they'll stick out inside the rollers * Alternatively, you can use wood screws that fit roughly into the holes * If you're feeling adventurous, you can even go without screws altogether ### Credits ### I've created these models from scratch, but I've been inspired by many other designs along the way Two really nice ones stand out in particular: The idea for the wide universal roller comes from https://www.thingiverse.com/thing:629381 The system for fastening the bracket to the printer frame is borrowed from https://www.thingiverse.com/thing:1832235 Please consider downloading one of these designs if this one doesn't fit your needs __ _See printing notes and post-printing instructions below_ __ ### * Please post a Make if you make this! * ###
