InventShack + Your 3D Printer: The Perfect Companion

Most families who buy a 3D printer run out of ideas after a few prints. InventShack gives your printer a purpose — AI-designed projects where you print the custom parts and we ship everything else.

Already Own a 3D Printer?

You spent the money on a 3D printer. You printed a few benchys, some phone stands, maybe a figurine. Now it's sitting on a shelf collecting dust. Sound familiar?

The problem isn't the printer — it's the projects. Downloading random STL files from the internet gets old fast. What your printer needs is purpose — real projects that combine your 3D-printed parts with other materials to build something meaningful.

That's exactly what InventShack provides. Our AI designs complete builds that use your 3D printer for the custom components — gears, brackets, mounts, connectors — and we ship the parts you can't print at home: laser-cut birchwood panels, screws, springs, and rubber bands.

How It Works

1

Design Your Kit

Use the AI design studio to describe what you want to build. The AI engineers a complete kit.

2

Print at Home

Download the 3D print files and print the custom parts on your own printer. Standard PLA works great.

3

We Ship the Rest

We send you the laser-cut wood panels, screws, springs, rubber bands, and instructions.

4

Assemble

Combine your home-printed parts with our shipped materials and build the complete project.

What You Print vs. What We Ship

You Print

  • Custom connectors and brackets
  • Gear assemblies and axle mounts
  • Spring seats and cam followers
  • Decorative elements and custom shapes
  • Wheel hubs and bearing housings
  • Launch mechanisms and winding keys

We Ship

  • Laser-cut birchwood panels (up to 12"x12")
  • M3 screws (8mm, 12mm, 16mm lengths)
  • Hex nuts and washers
  • Rubber bands (various sizes)
  • Compression springs
  • Step-by-step assembly instructions

Printer Compatibility

InventShack companion builds work with any FDM 3D printer with a build volume of at least 6"x6"x6". That covers the vast majority of consumer printers — Ender 3, Prusa, Bambu Lab, Creality, and many more.

All parts are designed for standard PLA filament — the most common, cheapest, and easiest-to-print material available. No special nozzles, heated chambers, or exotic materials needed.

Why Companion Mode Is Great

Save Money

You provide the 3D printing, so the shipped kit costs less. Your printer pays for itself through real projects.

Build Faster

No waiting for 3D-printed parts to ship. Start printing immediately after your design is ready.

Learn More

Kids learn 3D printing skills alongside mechanical engineering. Operating the printer becomes part of the build process.
