Our Capabilities
What Can We Make For You?
We work with ranchers, small businesses, inventors, and makers across the Bitterroot Valley. Whatever the project, it starts the same way — tell us what you need.
I need a part reproduced
Send us the CAD file and we'll print it. Need a file created from the original piece? We can do that for an additional fee.
I need a design file created
Don't have CAD files? We can create them from your measurements, references, or specs. File creation is an additional service.
I need the same part made over and over
From 10 to 10,000+ pieces — consistent quality, competitive pricing, no tooling costs.
I need something that has to hold up
Outdoor use, heat, flex, mechanical stress — we'll match the material to what it has to do.
I need a prototype before I commit
Get a physical version of your idea in hand before you spend money on production. Typical turnaround is 2–4 weeks.
I need engraving, stickers, or CNC work
Beyond 3D printing — laser engraving, custom stickers and vinyl, and CNC woodworking for signage and parts.
Family-Run Since Day One
Our Workshop
We're a family based in Hamilton, Montana. Five sons, a shared interest in making things, and a workshop that's grown into something real.
We've printed replacement parts for Bitterroot Valley ranchers, prototypes for local inventors, production runs for small businesses, and everything in between. The jobs vary. The approach doesn't — your project gets personal attention, not a ticket number.
You don't need to know anything about 3D printing to work with us. Tell us what you're trying to solve and we'll handle the rest.
