Bicycle Handlebar Storage for aluminium barends

These storage tubes fit into a standard mountainbike (and probably trekking/roadbike) handlebar.

You'll need barends like these:

You'll need the lower part (aluminium plug) and the screw, as well as a threaded insert (should be M4 - I think you could theoretically reuse the one they melted into the upper plastic part).

The printed part has a thinner section that works both as a  support and to keep things in place.

You need to cut it away or cut it free on the lower end after printing.

I keep a tubeless repair kit in one of the two storage tubes and zip ties, a chain link and a valve removal tool in the other one.
