This model is made to be used with 20mm tall 3M command strips. You might have to trim the strip a little bit to fit. If there's interest, I will be happy to change so there's screw hole cut outs.
This model will accommodate US Pool, Snooker, or Billiards (3 cushion) sized balls.
Printed mine with transparent PETG at .20mm height, 15% infill.
