Prusa i3 MK2/s & MK3 and Lack Enclosure Threaded Spool Holder
thingiverse
Inspired by @pauloremigio's Simple Spool Holder, I wanted one with a threaded nut to lock the spool in place securely. Includes threaded and unthreaded washers as well as a threaded nut to lock the threaded washer on tight. Update: Confirmed it fits the MK3 perfectly. Do not tighten the washer/nuts against the spool, the spool should turn freely. Instead, use a threaded washer and nut on the one end and tighten them against each other to create a barrier on the left side of the spool. You can also put an unthreaded washer on the right side if you wish. Update 1/5/2019 I've recently built a Lack enclosure for my MK3 so I've added a new base that you can bolt to the top of a lack enclosure and keep the same threaded design.
