About this 3D model
V2 Ears just released https://makerworld.com/en/models/1092287#profileId-1085930 We're going to Disney on ice in a few weeks and wanted some different Mouse ears. These have a magnetic clip that you have under your hat or whatever you happen to have on and the ears simply clip on. Each is run from it's own Gemma M0 board with a 500mah battery + lithium charger. The circuit can be adapted along with the code to include a ballswitch or something similar which can then run a different lightshow. For the light dfiffuser i cut up some milk bottles to fit the shape of the front insert.
