A tubing support, alignment, and length-setting jig for the Kobalt 1-1/4-in Poly Tube Cutter Item #2146972 Model #58702 available at most Lowes locations. Supports tubing from 4mm (includes two fixed length blocks for Qidi X-Maker and X-One2 models) to 16mm OD FEP, PVC, or Silicone tubing. Designed primarily because the more common "soft tubing cutters" that people use for PTFE tubing really hurt my hands after a while, and I got nowhere trying to design a good jig for them. Poly-cutters are much stronger and support a wide range of tubing sizes as well. The bridge print helps to center the blade prior to cutting since the axle pin allows a bit too much slop in the blade. CAD files are included if you want to make jig blocks for other diameters and fixed lengths. The blocks height when printing needs to be set to your target length minus 0.040" (1mm) which is half the blade slot width. Prints assemble with for 4-40 screws driven into the jig blocks.
