Split piece ball stretchers available in three diameters and three thicknesses. Load the desired file into your slicer and split the part before slicing as each STL file contains two different halves. One half has integrated threads and the other has the space for the recessed bolt.
Assemble the pieces with two M5x0.8 socket head cap screws 10mm - 16mm in length - the longer bolt you can use, the easier it will be to assemble and better it will hold.
Diameter size:
Small - 30mm Inside diameter
Medium - 35mm Inside diameter
Large - 40mm Inside diameter
Thicknesses:
Small - 12mm
Medium - 18mm
Large - 26mm
