Fidget triangular toy (infinity)

Similar to a fidget cube. An infinity toy suitable as a gift. Very entertaining and popular in class.     Fidget Widget - YouTube       You need 6 pieces to make a toy (you just have to put one inside the other to assemble), - I suggest 3 blue and 3 black. I printed with plain pla, nozzle 0.4 mm, infill 15%, no supports.
