MPMD Improved Extruder Fix

thingiverse

This is a side product of my top plate for flexible filament for the MPMD, basically the mk3's mount solution as a stand-alone. It was designed to address an issue with the PTFE tube jumping every now and then when printing non-flex filaments with Spconnol's extruder fix integrated. Research revealed that it was originally designed for an inward-mount. To mitigate this problem, I reversed the direction of the screw and gave it a bit of straight distance between the points where there is friction held, making slipping much less likely. To print the threaded tube successfully, make sure you print it standing up on the smaller side. This ensures that you don't have any cleanup trouble while maintaining maximal structural integrity. I've had excellent results printing the tube part in PETG. ## Changelog * mk2: The first iteration would sit a bit loose in the stock extruder plate and some filaments would make it wiggle enough for the ring that was holding it to break off. This new version has a beefed-up ring that fills out the whole space in the stock extruder plate, making it much more stable. It also features a standoff plate that adds more stability when turned towards the printer. * mk1: Initial release
