Holds up to 23 R8 Collets. With the feet installed, it holds the collets up at a 30 degree incline. I intended for the feet to be glued in, but in my print (granted, it's ugly...don't judge me, I used up some old PETG filament knowing it's just gonna get beat to hell anyway :) ) You can check out more of my toolbox builds here.

Everything should print fine without any need for supports, etc. If you want to play it extra safe, you may want a brim on the short legs, but they have a decent contact patch. Depends on your material, printer, and preference, I suppose.
