42 - Version16

The Answer.

Also, just having fun trying out a some 3D CAD and printing ideas. More versions on the way.

This one : 42 Coin

Forty two Altairan dollars, legal tender anywhere in the galaxy. The coin is 42mm in diameter; the milled/reeded edge has 42 serrations.

Print instructions

Print in PLA using the 3mf file provided; otherwise :

- perimeters =3

- infill = 100% rectilinear

- speed (Bridges) = 20mm/s

Print dolphin side down with no supports. I reduced the speed on bridging from 30 to 20 mm/s to help improve the print quality.

The first layer prints some very small bits, so a clean print sheet with a bit of glue is recommended to get good adhesion.
