I use large amounts of heatshrink tubing, because I work with automotive and boat wiring. I didn't want to invest in a highly specialized and expensive cutter for it though, because it's way too expensive. I managed to reduce the time I spent cutting heatshrink tubing to size by about 60% by making this cutter, which is made to fit on top of a stackable container like these, by DesignByLibb:
The files as supplied are printed in PLA without any modification to settings, on an Elegoo Centauri Carbon. Be adviced that you may have to mess around with settings for your specific printer to get the tolerances you prefer. The "holderdowner" holds the smallest heatshrink tube a bit tight, and the largest ones I use (Ø=25mm) a bit loose, adjustable tensioning might be an idea?
Let me know if you improve on it, so I can download and test your version! :)
You need the following parts in addition:
9 x M3,2x10mm screws - for assembling the length stop, the infeed "holderdowner" , the knife blade clamp and for the blade holder return spring
3x M4x50mm bolts - for the thumb screws(cut to length, unless you want to buy several lengths of screws.)
4x M4 flat washers - for the thumb screws and to retain the blade holder return spring
3x M4 nuts - for the thumb screws
1x M5x40mm bolt - for mounting the blade holder to the base
1x M5 lock nut - for mounting the blade holder to the base
