Training Spheres for Grip-Strength

thingiverse

I crafted custom training orbs for grip strength exercises. You can access downloadable STL files for spheres with an 80mm diameter, as well as an SCAD file that allows you to adjust the diameter according to your needs. I cut the orbs in half for improved printing ease; simply glue the two parts together once printed. To attach the orbs, approximately one meter and eight millimeters of climbing cord will be required. Simply thread the cord through a hole, secure it with a fisherman's knot on one end and a double bight figure-eight knot on the other end.
