Mechamouth Phone Holder is a very strong phone holder that can be fixed to your cockpit by adding a double adesive tape (nano tape is good, like this: Nano tape on Amazon).

You can print it with few support easily to remove.

I have printed it in PLA and it demonstrates very strong clamp/bite to hold the phone. I open the Mechamouth and inserted my S23 Ultra with ESR cover.

In case you print it in PETG or ABS, please let me know the result!
