A ribbed push-in plug that caps off any round tube - bike bar-ends, furniture and chair legs, railings, fence posts, or any open pipe. The flexible barbs grip the inner wall while the flange sits flush as a clean finished cap.

Just push it in, the angled barbs compress on the way and lock against the tube wall, no glue or fasteners needed.

Features

• Push-in fit: flexible barbs grip the inner wall, no glue or screws
• Clean finish: flange seats flush against the tube end as a visible cap
• Even ribs: barb spacing stays uniform for any fin count
• One part: works as a bar-end plug, furniture foot, or pipe cap

Default Dimensions
The default settings fit standard road bike handlebar ends with thick bar tape (~3 mm) wrapped into the bar end.

Using thinner tape or no tape? Increase fin outer diameter so the barbs still press firmly - the plug is what locks your tape in place.

Customizable Parameters
This is a parametric model - every dimension is adjustable, each parameter has a description in the customizer. The key rule for a good fit: set the fin outer diameter ~0.3–0.5 mm over your tube's inner Ø, and the flange diameter larger than the tube outer Ø so the cap seats as a stop.
