About Us

Hi! I'm Adam Stephey and Yodelhaus is my business. 

I've been creating since I was just a wee lad playing Legos on the living room floor. As a young adult I lived in Germany for five years. When I moved back to the Midwest I learned how to build furniture from my grandfather and taught myself 3D drafting. 

I also grew up with Super Mario and Sonic the Hedgehog. As a young entrepreneur I developed a line of cleaning products for retro video games and systems called 1UPcard.

In 2017 I launched the Toilet Timer which was successfully funded on Kickstarter. Then in 2018 I started my line of 3D printing accessories. Frankly I can't wait to see what comes next. Thanks for stopping by!
