Shrink tube cutter

myminifactory

This is a tool I made to make it easier to cut several pieces of shrink tubing at the same length. It can handle up to 30mm wide tubing and to 120mm length. It is designed to use a window scraper type razor blade. M6 bolts are used for alignment (I tapped the threads right into the material. It's important to make sure they are as straight as possible.) There is also a recess under the plunger part in the bolt holes to accommodate springs. The measurement lines are at 5mm intervals (the first is 15mm from the blade.) It's possible to cut other things like rubber tubing or other materials that are soft enough for the razor blade. I printed it in PLA at 0.3 layer height, but maybe 0.2 would be nicer. Supports were only used on the plunger part. It works great in PLA, but I recommend a stronger material if possible. (PETG or ABS)  Thanks for looking. Hope this can be useful for others. Feel free to share or give as a gift.
