Galaxy S8 car holder (Spigen Rugged Armor)
I designed this holder for my Samsung Galaxy S8, which I protected with a Spigen Rugged Armor. It is loosely based on the Galaxy S5 Thermal Mount.
All buttons and ports are easily accessible. Hexagonal holes in the design allow for better cooling.
I included an adapter for single-prong suction cup bases. You can browse Thingiverse for different adapters that might suit your existing base.
There is also an adapter for ball-socket mounts, thanks to Coder-Tronics.
