Uses a 3d printed-in-place spring to allow snugly snapping a 3/4" / 18mm dowel rod into position. Won't pop out under normal use and it allows you to add or remove tape rolls while preserving that precious vertical space under your cabinet.

Maximum thickness of tape roll measured from the inner to outer diameter is about 40mm.

Printed in PLA with 2 wall loops and 15% infill.
