I was looking for a DualSense controller mount that would clamp to my end table and also be very stable. I couldn't find exactly what I was looking for, so I remixed a few different items to get what I wanted. I pulled the clamp and the screw from Dualshock PS4 Controller Holder - Desk Mount Clamp by eltoroloco04 and stuck the male mounting bit from Tools Tray by IGUIGUI on it, and finally, I merged the two halves of the mount from HSW PS5 Controller Mount by Jungl3 and stuck that onto the female half of IGUIGUI's tool tray. The end result isn't pretty, but it solves the problem in the way I wanted it solved.
I printed the screw sideways with supports. It'll print just fine if you print it standing on the head, but since the layer lines are aligned with the threads, it makes it very likely to snap off at the head when you tighten it.
The cradle I printed in it's final position, with supports, and the clamp I printed laying on its side (with supports).
