This easy print was designed to be made with flexible filament for some Halloween fun. Use them as party favors. It hardly uses any filament to print. There are 2 versions, one with finger holes and one with a hook to hang it from the ceiling or chandelier as a decoration.
One bat has longer slits to accommodate bigger fingers. Video of bat flapping here
I create these designs to encourage people to try out flexible filaments or get some new interesting colors of flexibles. For info on purchasing samples of several brands of flexible filament, TPU for as little as $1.99 per sample see 3dprintny.com (USA Shipping only)
