Massage Ball Roller

thingiverse

This is a roller designed specifically for massaging sore muscles. It breaks down into three distinct components, each one printed separately. The base and central piece can be produced with relatively coarse quality settings, but I strongly recommend printing the ball using fine layer heights to achieve optimal results. Once they're off the printer, place the ball inside the middle piece and gently push on the base until it fits snugly in place - mine required some friction to secure, but you might need to add a small amount of adhesive for a tighter seal. Before assembly, lightly sand the ball to ensure a smooth finish. Then, quickly put everything together while the layer lines are still fresh, allowing the device to build up friction and dissolve any imperfections.
