Rocket keychain onshape design from an internet image.
3 files: 1 - Normal Rocket: for printing with a normal printer with a single color or multicolor. 2 - Rocket 1 - 2 and 2 -2 : to print with AMS / MMU2 in double color.
I printed it at 0.3 layer height with a 0.4 nozzle at 15% fill.
It needs to be flipped, I designed it on the front plane.
The original design is a little big, you can scale it on the Y axis to 70mm to make it look nice and not so big. The Z axis I put it at 4mm, it's a thickness I like.
0.2mm layer, 2 walls, 15% infill
