GraviDispenser

A marble dispenser for Gravitrax. The beaker can hold about 30 marbles. If it's full, you run a good chance that the marbles block each other and you need a brief stir.

There a two versions:
Version 1 uses a spring ("Feder") which must be printed with TPU (I used 98D). The spring is inserted from the top with the "double-bar" down.

Version 2 is an all-PLA print. The sprind is inserted into the two little slits left and right down from the marble outlet.
