Building the Tools that
nobody else will.

A one-man shop in a converted shed in Renton, WA. I started Madison Innovations to make the specialty tools I wished existed back when I was in the field.

Tools that work.
Or I make it right.

Tools need to work right every time. If one of mine breaks, send me a picture and tell me how — I'll replace it, and I'll use what went wrong to make the next batch better.

01
Made in the USA
Everything is designed by me. All 3D-printed parts are made in-house with USA-made filament. I use USA-manufactured components wherever practical.
02
Right to Repair
Replacement parts will always be available. If I ever stop making a product or shut my doors, I'll open-source the design files so you (or anyone) can keep them alive.
03
Print your own parts
STL and/or STEP files for printed enclosures are available on request. Customize them, repair them, run a copy through your own printer — go nuts.
04
Built on feedback
I take ideas seriously and refine designs constantly. If you have an idea for a Thing that would make your job easier, send it over.
From the maker
Hi — I'm Tyler. I make these.

Fifteen years in HVAC: started in building automation, then switched to mechanical startup and service (it's normally the other way around), and now in technical support. By day a tech-support hotline and instructor; by night an inventor and maker.

I design every Thing myself, including the electronics, then print it on the machines in my shed-turned-makerspace, test it against real jobs, and ship it myself. It's just me.

THE WHOLE PITCH
One tech. One shed. Four Things in the catalog.
Designed in the field.
Every Thing started on a job or a tech-support call — a small problem that needed a small tool nobody had made yet.
Printed by hand.
On the printers in my shed. Designs get refined batch over batch; the VRF Pipe Thing is on its ninth revision.
Shipped by me.
From Renton, WA. Every package is packed and labeled by me. Everything is backed by a 1-year warranty.
