This compact manual guillotine is designed for makers, 3D printing enthusiasts, electronics hobbyists, model builders, and craft professionals who need clean, accurate, and repeatable cuts.

The tool was originally created for cutting 4 mm PTFE tubes, but it is also suitable for heat-shrink tubing, electrical wires, drinking straws, bamboo sticks, and other small-diameter materials. The integrated adjustable stop allows fast and consistent production of identical pieces, making repetitive cutting tasks easier and more efficient.

Whether you're preparing Bowden tubes for a 3D printer, cutting heat-shrink tubing for wiring projects, or producing uniform lengths for model making and straw marquetry, this guillotine helps achieve precise and professional results.

Why Use It?

Cutting PTFE tubing with side cutters or scissors often leaves crushed or angled ends. This guillotine provides straight, clean, and repeatable cuts while significantly reducing preparation time.

The adjustable stop makes it easy to cut multiple pieces to the same length, improving consistency and workflow efficiency.

A simple yet highly practical workshop tool for anyone who values precision and repeatability.

Safety Notice

This tool uses a sharp utility blade. Always operate it carefully, keep fingers clear of the cutting area, and store it safely when not in use.
