Shrink Tubing cutter for any scissors

thingiverse

Update: replaced photos with new design. I had a bit of warping in the gauge piece. Should have used a raft! Always need to cut multiple pieces of shrink tubing for cable ends and they look much better if they are uniform in length. The little unit attaches to the one blade of any scissors and the user can adjust the depth to get the desired length. The magnet is a 15mm x 4mm round with a countersunk hole. I use a 4-40 flathead bolt that taps the plastic to secure the magnet. The adjuster is a 4-40 flat head(37mm long) with a nylon locking nut to keep it secured to the gauge plate, but still turns. The other end of the flat head screw self threads into the magnet/scissor piece to make the adjustment. Picture is of earlier version without guide pin strutting and the magnet is now recessed so scissors sit on rest bar. You may have to ream out the guide holes slightly depending on your first layer. magnet: http://www.ebay.com/itm/Lot-10-25-50-15mm-x-4mm-Hole-4mm-Ring-Disc-Rare-Earth-Neodymium-Craft-Magnet-N52-/311833824652?var=&hash=item489abe8d8c:m:mhd0guMizR3oV7jgtHoAw-g
