Nema17 stepper dampers

thingiverse

These are some dampers for nema17 stepper motors. I printed these in soft PLA but other flex filament probably work too. Apply z-scaling if they are too soft or too hard. (I used 20% infill). Goes well together with my printer coasters: http://www.thingiverse.com/thing:1625387 Update: It has been pointed out to me that a cutout from an old bike tire may work even better, but I don't have any old bike tires. If you do, please give it a try and report your findings :-)
