About this 3D model
Simple tool for aiding in the cutting PTFE tube to different sizes with consistent length and straight/clean ends. I previously made separate versions for 5mm, 18mm, and 30mm, but this version supports lengths the following lenghts all in one: 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, and 50mm. In case you want exactly precise length tubes, make sure to use an exacto knife blade with a flat edge pushed against the wall of the cutting guide (as in the picture). Few things to notice regarding printing: I'd highly suggest printing this on its side in order to avoid weak spots caused by the layer lines. Quality → Wall generation → Arachne. The “Classic” isn't able to properly slice the small texts. Only one filament changed needed at layer 41 (8.20mm), either manually or with the slicer if you want the texts in different color. No supports, brim, or prime tower needed.
