Es funktionirt shr gut

I made one, but how is it supposed to be used, since its exit does not match with the entrance of a marble tile on the next GraviTrax baseboard space? The exit of the ballista extends over the edge of the adjacent tile.

Looks awesome do you have to have a certain type of filament?

Já použil PLA a jako gumové pružiny proužky ustřihnuté z balounku

I used PLA and strips cut from a balloon as rubber springs

Works like a charm, just have to find the right rubber bands as the tension I have is too strong. The balls are really shooting out like from a ballista.
