Democracy bike stamp

Current status of the project:

1. The holder for the paint reservoir looks stable and good. Multiple length and types of arms could be printed from here: https://www.printables.com/model/185322-modular-mounting-system-arms-customizable/files
2. The paint bottle cap/roller seems to be ok, it could be adapted to different types of paints
3. We have an openscad script to generate the actual stamps to be fastened to the bike wheel.

The problem is that the stamps/paint combination doesn't work well. The paint is too thick or stamps material is not right. Too much paint or too few makes the painting unreadable.

Stamps materials tested:

• PLA
• PLAFlex
• Linoleom 

Paints tested:

• Gouache paint
• Stamps ink

Had no luck with these…

The design, if someone wants to remix and enhance, could be found on this onshape document
