Built in the Garage

NerdbillyFab started when I needed stronger wheels and adapters for my kids' Peg Perego tractor after the stock parts wore out. Friends kept asking for the same upgrades, so I started sharing designs.

I prototype, print, and test every part myself. If it's not plug-and-play, I don't ship it. Simple as that.
