Kẹp cài thắt lưng cho Note 20

Phone carrier for my Note 20 case.

Spring 28.11 x 4.63 (found in a clicker pen)

The space for the spring is 20x4.7mm

Most of the models have a flat side but still need supports, the Racks I would recommend adding a Brim 

Some light sanding is need as the tolerances are tight.

Add some kind of lubrication

The front does snap to the back but would recommend gluing it.

Included the Step file for the Back to adjust for the spring.

The model in the images were printed in  PLA but would recommend Petg or something stronger.

Edit- Forgot the gear.
