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.
