Three batches of Prototypes have been printed:

6 Blue & 6 Red prototypes in the first batch where for the kickstarter trailer video and marking system verification.

50 Blue & 10 Red prototypes in the 2nd batch for promotional purposes and testing of the adjusted marking system.

50 Blue prototypes in the 3rd batch to fix the funny mistake I made in the 2nd batch and take the opportunity to further tweak the marking system.
