Rubber Band Spinners
thingiverse
These band spinners are used in FTC games for gathering various items. They work best with thick rubber bands, preferably square or round in cross section. These cords work exceptionally well when tied off at both ends. https://www.mcmaster.com/1034t12 The four different sizes of these band spinners allow you to easily customize your spinner size. Optional zip ties can be attached to the top edges of the spinners, further securing the rubber bands in place. Troughs on the bottom of the spinners provide a secure resting place for the rubber bands and also hold them in place with zip ties. This lowers the width of the spool slightly. They work best with Actobotics D Clamping Collars and quarter inch D shaft.
