Based on @mattmaltarich idea i build my own rugged phone holder for my Ktm 890 Adventure.
The size is for Ulefone Armor 14 Pro but I attach fusion 360 project so you can make your own.
I needed a very resistant support, which could withstand dirt and offroad with a very heavy rugged phone with quick attachment and release.
At the moment I have provided 4 holes for the sw-motech Ktm navigator support
The holder uses a spring to lock the phone.
I try some springs 0.7mm/7mm or 0.8mm/7mm diameter.
Now I mount 3 spring 0.7mm/7mm/25mm (I can't find 70mm long spring)
Anyway you can easily change spring in any moment.
Now I'm working for a support with wifi charging module.
