Air Tag bike saddle rail mount

There are many design for this application but this is my version of Air Tag mount for bike.
I wanted to make minimal and a little hidden one since it shall not be too obvious in my opinion.

It utilizes the saddle rails to fix. (diameter 7mm, distance 43mm)

You will need following hardware.
- 2x M4 thread insert
- 2x M4-10 hex socket head bolts
- 2x 2.6-10 or 12 tapping screws

For printing, no support necessary. please ref the picture for the printing orientation.
