My friend's Onyx Studio 2's legs got broken off in a move, so i designed this to hold it. This is my 3rd iteration and is very sturdy, and allows plenty of access for the plugs on the back. I did notice that the filament was lightly scratching the finish on the speaker, so i glued some velvet in the part the speaker sits in.
I had to turn it 45 degrees, but it did fit on the build plate of an Ender 3 Pro.

I did some fancy settings with support blockers that let me print the front half with 40% infil so the bottom of the part the speaker sits in had enough to build onto, but the rear half used 15% infil to save some filament. it probably doesnt need that level of infil for structure, but the way the bottom of the cradle prints minght not work well with lighter infil.
I think i did the supports at 50 or 55 degree overhang, it didnt need supports all the way up the sides, but i think i did need them at the start.
