A roller for massaging your sore muscles. All that is required is a length of 1/2" wooden dowel, and access to a 3D Printer. The holes in the handles are tapered and will fit very tight when pressed down firmly, so make sure to cut the dowel about 4" longer than the intended length. Let me know what you think! I am planning on creating various widths, diameters, and handles if there is enough interest.
