Very nice module
Sin problemas en la impresión, a mi nieto de 6 años le encanta
Very enjoyable to watch, no problem to print it.
Firstly, this is a fun module! I love the all the motion you get with multiple balls going down the track. Lots of fun!
Secondly, if you haven't made yourself a marble machine, this is the way to go. Fun modules, multiple configurations gives you all kinds of combinations.
So what are you waiting for?
