Remixed the game clip so that it has a hinge and also designed a whole new holder for the Samsung Galaxy S8. I designed the whole thing from scratch based on the dxf file provided in the original thing.
Printed everything from PLA at 25% cubic infill 0.2mm layers. Print in the orientation the models are stored in. You need supports for both parts, choose 10% lines 'everywhere' in cura.
The hinge requires a 30mm M3 bolt with a head smaller than 6mm and a M3 nylock nut.
You need to use "SixAxis Controller" or a similar app from the play store to make the game pad work with the S8. This is a paid app which needs to run on a rooted handset to function best.
Gameclip.dxf is the original file I started with from bernabap's thing.
