Galaxy Note 10 hat mount.

thingiverse

I use a custom 3D printed holder made from semi-flexible filament to securely hold my Note 10, even when fitted with an Otterbox case. This design allows me to easily insert and remove the phone as needed. For added stability, I recommend printing it in a rigid filament and cutting off the top to accommodate the phone's size. This versatile holder gives me the freedom to capture high-quality footage of my RC plane flights without needing to physically hold the device.
