PTFE Sizing Guide

Created a tool that will allow you to make straight cuts of PTFE when smaller accurately sized pieces are needed.    The MMU2s kit was one of the projects I worked on that needed several smaller pieces of PTFE.   This allowed me to use a straight razor blade and cut it along the tool ensuring the same size pieces with a 90 degree cut.

Print Setup

• Layer size = .2mm or finer
• Nozzle Size = .4mm
• PLA / PETG doesn't really matter
• Infill 10%

Usage:

1. First cut put into the 5mm hole to get a good 90 degree cut on the tube.   
2. Then find the size based on the numbers on the side.  This is graduated in millimeters from 5 up to 30 mm lengths.
3. Using a straight razor blade cut the tube right along the sizing tool at 90 degrees to ensure an accurate cut
4. After the cut use one of the mid size allen wrenches that came with the Prusa tool kit to push the tube out from the opposite side you put it in.

Now keep in mind due to some differences in Z first layer squish the lengths might be off by up to .2mm but for most of the ones I have checked they have been much less than that and is fairly accurate.
