Always get a nice straight cut. Designed for 1" rolls of masking tape.

Measure the width of the roll of tape and pick a size slightly larger. Clean the holes with 1/8" drill bit. Sand or file the cutting edge along with a general clean up.

Snug up the 3 mm screw enough so it does not move around after use.

Hold cutting edge on tape for clean cut.

Measurements are a guide. Actual sizes may vary.

V2 has a curved underside for better fit.

Scaling the model is always an option.
