So here is a tiny bubble maker tube. Goal was to create more tiny bubbles in a blow and not big ones paired with smaller ones we are used to from normal wands.

Version one is overall too big and has the problem that it forms clusters of medium sized bubbles all stuck together occasionally that sink to the ground fast. Could be a soap solution problem as well.

Version two is overall smaller and the mouth part is easier to blow through. The holes are also more and smaller.

The files also include a "Deckel" german for cover. It fits both versions and can be used to fill a small amount of bubble solution inside for dipping and blowing.

Its not perfect, but my little experiment worked out and i will end it with this.
