Batman Batarang,

selfmade, obviously inspired by the batman movies but my own design,

i did not make the edges thinner, so you can kind of throw them without them always breaking,

maybe you have to scale a bit but not too much,

i printed with PLA but should also work fine with petg or other filaments

Settings: I used 45% Infill but should print fine with 20-100% (but the best for durability is probably 45%), 2mm layer height, 2 walls, no support, no brim

have fun!
