Customizable Round Tube End Cap

Generate an insert-style round tube end cap sized to hollow tubing, with adjustable diameters, ribs, plug length, and clearance.

Replace a missing cap on a hollow round tube, pole, broom handle, rack, or similar fitting. The ribbed plug inserts inside the tube while the cap rests over its edge, allowing you to fit the actual tubing instead of relying on a fixed-size end cap.

What to Measure
 - Tube inside diameter
 - Tube outside diameter
 - Available insertion depth

Use the Clearance setting to fine-tune the press fit for your printer and material.
