Universal Controller w/ phone holder fastener(Customized for POCO X5 Pro: Length wise)
Loved the ergonomics and feel, But it lacks support/clamp down for "all phones/Esp. with cases", Here is a solution to probably address the problem with the Clip. I haven't gone around to printing it, But feel free to slice the model and print only where your phone lie on. so you could test if its the correct length.
LENGTH: 10.6 inches/ 270mm(not original size)
