So I work at a TechShop now, which means I have access to lots of great CNC machines. The old gauss rifle files have been dusted off, and I’m giving them a go- here’s the first cuts of the gun.

Might try this with soft plastic soon, the MDF is a bit fuzzy to go straight into molding.

This was a test piece for my CNC, but I might as well make it available to everyone now- I know there are some others working on their own CNC machines to build armor with now, maybe it can help them.
Modeling was done in Cinema 4D, OBJ was exported from Pepakura 3. Included is an STL and C4D, as well as the basic model.

Recently finished a major upgrade on the mill; from 1/4-20 threaded rod to 1/2-10 acme leadscrews. Also eliminated couplers between the motors and leadscrews, pinning the motor shafts directly into holes lathed into the leadscrews. Fewer connections, and tighter tolerances of the new hardware has backlash down to less than .01″.. for MDF and cheap off-the-shelf parts, that’s good.

So, what’s that good for? Well, it makes programs run faster, and parts cut out faster, as well. That’s a good thing, because the carbine model I finshed recently is taking a long time to run- it had to be split up into about two dozen separate milled parts. As the carbine alone will be around 2-3 days of machine time, and there’s a queue of two other entire projects after it, it’ll add up to a lot of time saved.

Speaking of other projects, I’ve been updating the halo 3 marine files to be CNC’d, maybe they’ll hold up as vacuum-forming bucks.

Modeled purely for the gcode generation.

Thanks to Martyn Ball for the original 2k or so of tris, and Peter Lack for the expanded reference pictures.

I’m working on a Covenant carbine model, because there wasn’t one available in the resolution I needed for the CNC machine. I suspect I’ll have to do this with about everything I want to CNC.

Currently about 39,000 polygons. It’s a work in progress, but I hope to have it sliced up and start on cutting it out by next week.

Finally done with this. Oh, been working on it, too. Here’s an example of what it can do:

Rockcliff plans, HobbyCNC controller, MeshCAM toolpaths, & Mach 3 control.
That’s robogenesis’ model cleaned up a bit.

A long time ago I made a halo magnum model..
Recently someone named bigoz9 printed it out. In ABS plastic.

Next up is the sniper rifle.

Great stuff here.. came across these Fallout 3 powered armor suits, from a guy named Vampyredh. I cleaned them up some, and since I’ll probably never actually make them.. here, have fun.

There’s always going to be That Guy.
The guy who tries(ss) to write(ss) you(ss) out of the forum after you say something they don’t like. The guy who steals your work and reposts it with almost all of your credit(and others’) removed. The guy who jealously guards his work, letting only screenshots and snippets out. The guy who decides he should only release pdfs, because the latest version of his software of choice bit the bullet and wrote in model exporting.

I’m not going to be That Guy. Enjoy.

I’ve been working on models to build the Starcraft II marine suit from. The first step is to rough things out in low-polygon resolution, that’s about done.

Next comes NURBSing to smooth things out and add details with an eye towards accuracy, then modeling of the mechanical exoskeleton which will, hopefully, make the suit wearable. Might end up using some of those fancy Solidworks CAE tools finally, too.
