  • High-precision prototype service workspace showing a Carvera CNC machine and a Bambu X1C 3D printer on a tool bench, surrounded by organized tools. Highlights precision CNC machining, advanced 3D printing, rapid prototyping, and custom parts fabrication for engineering projects.
  • Workshop table showing the full prototype workflow: an idea sketch on a tablet, a 3D CAD model displayed on a large monitor, and two finished prototypes on the table beside calipers. Background includes CNC machines, 3D printers, and tools. Highlights the service of turning client ideas into real, functional prototypes using CAD, machining, and fabrication.
  • Custom 3D-printed jig designed for controlled fiber winding, mounted on a wire shelf. Long copper strands are tensioned across a curved fixture with indexed holes and bearings for consistent spacing. Used for coil winding, electromagnet prototyping, and small-batch fixture development.
  • Two-part image showing precision-wound copper coils made with custom jigs. Top: a continuous loop of alternating-color insulated wire laid on a mat. Bottom: a hand holding a compact laminated stator coil assembly with tightly packed windings for motors, generators, or induction prototypes.
  • Black experimental micro wind turbine from Daisy Power Systems with three aerodynamic blades, a compact generator housing, and a rear tail fin. Optimized for low-wind outdoor testing, energy-harvesting prototypes, and small off-grid power experiments.
  • Experimental Daisy Power Systems wind turbine mounted outdoors on a rocky coastline during high wind conditions. Three-blade rotor spinning against an ocean backdrop. Used to validate blade performance, charging output, and prototype durability in real environments.
  • Custom Prototype Service | Design, Fabrication & Testing
  • Close-up of a polished purple faceted gemstone demonstrating optical clarity and precision cutting. Used to showcase results possible from custom lapidary tooling, CNC-machined fixtures, and prototype gem-processing workflows.
  • Custom Prototype Service | Design, Fabrication & Testing
  • Green and black 3D-printed water-control nozzle attached to a repurposed plastic bottle, dispensing a clean stream of water. Includes eco-tech branding overlay. Prototype designed for outdoor hydration, garden use, and sustainable hardware product development.
  • Organized rows of white and orange 3D-printed thumb nuts on a gridded cutting mat, beside a tin of M3 bolts. Demonstrates small-batch production, hardware kitting, and rapid manufacturing runs for custom components and prototype assemblies.
  • “Close-up of a red custom 3D printed adapter mounted to a bench lathe polishing wheel, with a green rotary tool positioned for alignment. Shows custom fixture design for precision setups, jigs, and bespoke machining adapters used in prototype development.”
  • “Dual-wheel bench wet lathe system with black 3D printed housings, red guards, and integrated water trays. Built to demonstrate custom machine enclosures, attachment design, and engineered components created through the prototype process.”
  • “Stainless steel casting flask containing a purple wax sprue tree ready for investment casting. Demonstrates the shop’s ability to create prototype cast parts for jewelry, mechanical components, and custom metalwork.”
  • “Hand holding a small silver heart-shaped jewelry blank with a recessed center. Example of precision metal shaping and small-scale fabrication work available through the custom prototype service, including jewelry parts and bespoke metal components.”
  • “Close-up of a desktop CNC milling machine bed showing a precision engraving setup for custom jewelry. A small carbide bit hangs above a metal fixture holding a red 3D-printed jig with a heart-shaped silver pendant blank, with another matching jig and heart on the perforated work table, illustrating prototype machining for personalized jewelry parts.”
  • “Wide view of workshop shelving filled with fabrication tools, including a Carvera Air CNC, Bambu X1C 3D printer, casting machines, and filament spools. Highlights the full professional workspace used for rapid prototyping and custom part fabrication.”
  • “Workshop shelf holding a Carvera Air CNC machine and a Bambu X1C 3D printer, both enclosed and powered on, surrounded by organized tools and materials. Showcasing professional equipment used for custom prototyping, machining, and advanced 3D printing services.”

If you have an idea, simple or insane, I’m your huckleberry.

Every project starts the same way, with an idea.
Whether you're creating a one-of-a-kind gift, developing a product, restoring something meaningful, building a prototype, or bringing a personal project to life, every project begins with a conversation and a willingness to explore what's possible.

The challenge is always the same:
How do you turn that idea into something real?

You don't need engineering experience. 
You don't need CAD files. 
You don't even need to know how the process works.

Bring the idea.
I'll take it from there. 

The displayed price is a refundable build-slot deposit. It reserves project capacity and is credited in full toward your final project total. A print-ready part, a new mechanism and a multi-process assembly demand very different amounts of design and planning, which is why the deposit levels differ.

Not sure where your idea belongs? Tell us what you want it to do before reserving a slot.

Ideas we can explore

  • Functional product prototypes
  • Organizers, inserts and enclosures
  • Jigs, fixtures and workshop problem-solvers
  • Replacement or upgraded parts
  • Jewelry concepts and casting masters
  • One-off experimental builds

What helps us begin

  • Sketches, photos, files or reference links
  • Approximate dimensions and quantity
  • What the object must do and where it will be used
  • Known materials, loads or compatibility requirements
  • Your target date and approximate total-project budget

How the build moves forward

We review feasibility, fill in missing requirements and recommend a manufacturing path. You receive a written scope, final project total and schedule before production. Design labor, materials, fabrication, finishing and shipping are included only as stated in that scope.

If it is simple, great. If it is complicated, even better. Those are my favorites.
