The story

Why this exists.

The Problem: Eyeballing pipe sizes is not accurate enough to ensure a proper installation and identifying the size can be cumbersome.

The Solution: Have a specialty sizing gauge that lives on your keychain and is always at hand for rapidly and positively checking the size of your lineset.

For larger orders please contact me directly at tyler@madisoninnovations.com for pricing and customization options.

Proudly made in the USA with USA made material.

why PCTG? Higher chemical resistance, durability, and temperature range than PETG. Costs a little more. Worth it. Made in the USA.

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.
02
Right to Repair
Replacement parts will always be available. If I ever stop making a product, I'll open-source the design files.
03
Print your own parts
STL / STEP files for printed enclosures available on request. Customize, repair, reprint — go nuts.
04
Built on feedback
I take ideas seriously and refine designs constantly. Send me an idea for a Thing that would make your job easier.
