Curly Girl Wipeout Key fob!
Any Any Flexible or Other
White & Red
Compact key fob size of 85mm wide by 30mm tall by 4mm deep.
Pause to switch filament colour (from white to red) at 2.2mm+ or 50%+.
I print using flexismart filament at 100% infill to give it a 'substantial feel' but any other material will do.
Please note I am not the copyright holder of the logo or name. Licence for this thing set to non-commercial (no printing for re-sale please).
Use a standard cheap keychain for this one (available from internet auction sites).
