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.
