I play a lot of a game called WingFighter, and I hates that I have to grip the phone at the same time as playing. This model solves the problem and provides a pressureless method to hold the phone while gaming with a stylus in the other hand.
The grip also doubles up as a desk stand and its really good for photo taking, although that was never intended, it just worked like that :)
Its designed for Pixel 8 in the bellroy case and the Sandstrom stylus. It has been tested with a caseology and it also work, just a bit snugger than intended.
It is designed to be snug, but not tight, it will tolerate being used on its side but not upside down - the phone will fall out over time!
Method:
Print the body (with tree supports) and handle part, the handle is a zero tolorence fit to the body, so slide it in from the side and then apply pressure to clip it in place. This will depend on how tuned your printer is to how well it fits. Sanding and a bit of glue may resolve this for you.
Designed in Sketchup, hence no fillets but i will include the sketchup file to be changed to fit other phones - should be pretty straight forward to adapt it i think!
