Hi, this is my Focusrite Scarlett 2i2 holder, angled for 15 deg. Now I have more space for keybord, and little storage for guitar picks etc. I've made only one piece for myself out of PETG. It is designed to fit perfectly in the slot, you can take off rubber feets of the device or squeeze it in - horizontal bracket needs to be bent. It fits both ways. Cheers!
