Summary

This was designed for a Lezyne Pocket Drive HV pump. Needed it to fit in line with the top-tube and be mounted with only one screw.
I didn't think of publishing this but it came out so nice I thought others might want to try.

Printed out of ABS+GF. It's really sturdy, light and slim. Really nice addition to your gravel bike :)
