Minion Bristlebots

thingiverse

my own take on the classic bristlebot, with a 3D printed battery holder. Needed: 1 toothbrush 1 vibration motor 1 CR2032 battery hotglue (googly eyes) Instructions step 1: cut the head of a toothbrush step 2: print the battery holder step 3: attach the vibration motor to the battery holder and put the 2 leads into the holder block so the battery can touch it. step 4: hotglue the holder to the toothbrush head step 5: cut (if needed) the toothbrush hairs to length and bend them backwards so the bristlebot will go forward instead of in circles. step 6: decorate and race!
