Rigid Fibre Guide Bar for Markforged

cults3d

This part fits over the magnetic end cap for the reinforcement fiber roll for a markforged printer (Tested on Mark 1). The cross bar stops the rigid fibre from exploding out, and the nub on the bottom stops any reciprocal flexure on the opposite end from slipping over the side. I've been printing with carbon fiber as the reinforcement fiber on a Markforged Mark 1 recently, and I can't turn around for 2 seconds before this rigid fiber flies off the spool and wilds out into the build volume like someone just opened a can of peanut brittle only to find that it was full of spring-loaded snakes! I slapped this on my spool, and now I have no more problems with it.
