Hello, enjoy my creation for my father-in-law. I used this holder for drink shoot with diameter MAX 30 mm. Holes for shoots are 32 mm. (Keep a little tolerance)
You will need one 20 mm bearing to use the swivel stand. Usually used in roller skates, etc ... You will need one 4 mm screw to screw in the top bracket.
I used PETG with normal settings. You don't need support.
