Odd and Even ring sizers
thingiverse
I used the awesome tool listed here to make the ring sizers I want for my classroom. Print two of each and then rubber band them together to put them to work. The nifty thing is if a finger gets stuck you can simply undo the rubber bands. No dish soap required. =) Customized version of http://www.thingiverse.com/thing:312419 Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=312419 Instructions Using the following options: first_ring_size = 4 ring_w = 8 generate = 2 ring_size_incriment = 2 ring_thick = 2 num_rings = 5
