MMU2S/MMU3 PTFE Tube Organizer/Guide

prusaprinters

Holds your PTFE tubes from the MMU2/MMU3 nicely parallel - which helps to reduce friction. The part does not actually clamp the hose, but the friction should be enough to hold it in place.The model allows you to choose either an M3 Square Nut OR an M3 Hex Nut to keep it closed. Do not add too much torque to these screws, they just need to keep it closed, you do not want to add pressure (and thus friction) to the ptfe tubes. PrintingThese print best at a 0.2mm layer height, using 15-20% infill and 2 perimeters. No supports are needed, all overhangs are well within MK3S/MK4 tolerances.Required hardware2 x M3x10mm (from amazon individually, or as part of this kit)2xM3 Square Nut (amazon) or M3 Hex Nut (from amazon individually, or as part of this kit)The links above contain affiliate referrals.

Note: Do not use both, the screw could bind.Insert the nut into the appropriate opening.The square nuts are a tight fit intentionally, the best way to insert them is to start them in from the top, and then turn the part upside down and push it down onto a flat surface. Then use a precision flat-blade screw driver to push it down the remainder of the way.The hex nuts may be installed using the Josef Prusa nut-pulling technique - start the nut into the hexagonal hole, then insert a screw from the opposite side and tighten it until the nut is fully installed. Be careful not to over-tighten it, or you could crack the part!Hold the half with the m3 nuts under the PTFE tubes, and insert the tubes from one side.Add the top on loosely, and insert one M3x10mm screw until it bites into the nut.Spread the remaining PTFE tubes evenly across the partWhile applying light pressure, add the remaining screw to close the part around the tubes.Post-InstallationTake a picture of the part installed on your printer.Return to PrusaPrinters.org and post a make to this item! You'll get free PrusaMeters, and I love seeing my parts at work!Consider leaving a heart on the print if this helps you.
