PrintrBot SImple Metal Spool Holder

thingiverse

The original 100mm Spool Holder by Lentic served me well as one of my first prints for my Printrbot. However, the high-pitched squeak of plastic on plastic from the reels on the spool holder drove me insane. I resolved to silence it once and for all. To that end, I attached a roller with bearings and a tray to provide additional support. Initially, when I simply mounted the roller directly, it imposed too much stress on the mount, causing it to sag rapidly. This addition provides the necessary extra reinforcement to prevent that from happening.
