The grip is enough to hold the phone, for example, in cars and for filming, but might not have the grip strenght for stronger vibrations. Designed to incorporate two M4 screws in the back for mounting, but is not necessary.

I will use this model to mount my phone on shopping carts and in my car.

I will upload two different models, one with bumpers to add friction, and one without, where you can add rubber pads to increase friction if needed. The front plate is not necessary but provides protection.

When assembled the print slides relatively easy, but the slides might need to be sanded depending on the printer. No supports are needed. The spring is recommended to print in PETG to uphold its strenght over time

Feel free to edit as you like and post a remix. Comment if you got ideas for improvements :)
