It works extremely well... I hate when I don't see a picture of the real thing but I promise that it printed perfectly for me and the tolerances were perfect at .10 - .20 where needed. The screw is a little tight but it loosens after use.

I designed this in fusion 360 from scratch but I did reference another person's design and ingenuity (soooo... is it a remix?): https://www.thingiverse.com/thing:3450929

Print the Pads in TPU and the rest in PETG or PLA. I doubt they pads will fit if you print them in anything but TPU, but you can always put a little heat to it and make it fit.

Eventually I will add a modular component to the back, but for now you can modify the back plate file to fit your needs.
