2003 Dye DM3 Matrix models. Some may be compatible with the previous Matrix versions, but I don't know which in specific.

Part: DM3 body

Formats:
Inventor 10 part (.ipt)

Created by: Ydna
Description: DM3 body. I'm not exactly sure if the cosmetics are correct (I made this from a milled body) but it shouldn't matter much. Not all the threading is present.

Inventor 10 part (.ipt)

Created by: Ydna
Description: Air chamber manifold plug (three of the four plugs).

Part: Manifold plug (long)

Firing Assembly:

Part: Bolt assembly

Description: This model includes each of the firing assembly's components in a 3d solid view. Each component has its own layer so they can be altered or moved around independantly from the others.

Common parts:
Check the CAD file post index for links to universal parts which are compatible between multiple markers. This may include feednecks, regulators, air fittings, solenoids, and others.
