A simple holder to avoid having to carry an u block in your backpack.

It is angled so the u block sits on the seat, and you can secure the u block with a piece of velcro.

It uses 4 mm screws and bolts between the holder and the fixation, and uses the original screws under the rear fender.

Printed in petg-cf 0.2mm layer height with 15% infill and 5 perimeters
