LOC. MARBLE FALLS, TX

Performance parts,
engineered from scratch.

CAD Monsters designs, engineers, and builds precision hardware of nearly any kind, with a primary focus on performance automotive parts; custom intake geometry, full cylinder heads, mounts, and bell housings. Every part starts as a fully modeled, production-ready CAD design.

02 / Design Services

Got an idea? Let's make it.

Alongside our own product line, we take on contract CAD and build work, automotive or not. Bring a concept, a sketch, or a physical part, and leave with manufacturable parts.

/ 01

3D CAD Design & Modeling

Parametric SolidWorks models built clean and production-ready, not just pretty on screen.

/ 02

Rapid Prototyping

In-house 3D printing for fit checks and functional prototypes before committing to metal.

/ 03

Reverse Engineering

Turn a physical part into accurate, editable CAD, using in-house 3D scanning through our partner or your own scan data.

/ 04

Custom One-Off Builds

One-off parts and assemblies for almost any application, automotive or otherwise. If it can be modeled, we can build it.

03 / How a part gets built

Design to metal, in four steps

STEP 01

Design

Every part is fully modeled in SolidWorks before anything is cut. Existing hardware can be 3D-scanned and reverse-engineered first.

STEP 02

Prototype

3D-printed prototypes verify fitment and function on the actual platform.

STEP 03

Manufacture

Production runs are machined and cast through our CNC and foundry partners.

STEP 04

Deliver

Inspected parts ship direct, with fitment notes included.

04 / The shop

Built by an engineer, not a storefront

CAD Monsters is a founder-led engineering shop run by Anson Hoffman, a mechanical engineer out of Arizona State University. The company designs and develops its own line of performance automotive hardware, and takes on custom design and build work of nearly any kind.

Product development is funded by professional contract CAD work, meaning every design that leaves the shop, whether it's a client's part or our own, is held to the same engineering standard. We model in SolidWorks, prototype in-house, and manufacture through trusted CNC and foundry partners.

“

I started CAD Monsters with one thing in mind: turning ideas into reality, whether it be my own or others'. With a genuine passion for 3D design, I aim to do just that through the skills I have acquired in my many years as a designer.
