MMU2S PTFE Kit

thingiverse

Here is a full tool kit for cutting and trimming new PTFE tube for all parts of the Prusa MMU2S and i3 MK3. Cutter Only the Cap needs supports. The End Stop was left slightly longer than needed to allow for sanding/filing to fine tune the exact length(MAKE SURE YOU TEST AND ADJUST OR YOU'LL CUT SHOT). The body has a 19mm(MMU2S pully body) and 44.3mm(i3 MK3 Hot End). Should accept any razer that is less that .4mm thick. OD Chamfer Tool Has a slight adjustment from the Prusa recommended 60 degree angle to a 75 degree. It uses an M3x3mm(Don't go longer as you will screw into tubing guide, can omit if blade fits snug enough to stay in place while trimming. Just make sure the back of the blade is flush with the bottom of the screw hole). ID Chamfer Tool Should have a tight enough tolerance to snuggly fit a 2mm chamfer tool, if not the two ends can be pinched to hold it tight while trimming. Make sure the negative spaces are positioned centered with the side cutouts to allow shavings to come out and not jam up the tool. A second ID guide can be printed to hold short tubes for trimming.
