this is a slideout controller for any phone or case that has magsafe it can be added and removed at will as its attached to the phone with magnets i made this for my s20fe with a magsafe case and will soon be moving to iphone hense the reason for magsafe i will add the f3d files for people that want to remix it for their phones as far as the controller goes it was made to use the 8bitdo lite 2 it is stock other then removing the outermost backplate also it should fit most phone cases if not msg me and i can try to help 

as for parts you will need 5x3mm magnets about 83 but you should be able to use less this is what i used
