Focused, hands-on courses built for 3D printing hobbyists who want to move beyond downloading other people’s files and start engineering functional mechanical devices.
We create structured, project-based courses for 3D printing hobbyists who are ready to go beyond downloading other people’s files. Every course includes a clear outcome, a daily roadmap, and a real mechanical device designed and printed from scratch.
FEATURED COURSE
From 3D Printing Novelties to a Working Mechanism in 3 Weeks.
3 weeks of guided daily build lessons — about one hour per day, Monday through Friday
Guided gripper project — design, print, and assemble a working scissor-linkage mechanism from scratch
Design an original mechanism in Week 3 — something created from scratch, not downloaded
Tolerance Reference Kit — PDF cheat sheet + printable test file included
$99 $I99
PRE-LAUNCH — 50% OFF

I've been obsessed with how mechanical things work for as long as I can remember. As a kid I was sketching gears and mechanisms in notebooks — I couldn't stop. When I took my first Mechanical Engineering class and saw that I could design and manipulate parts on a computer, everything clicked.
I built my first 3D printer from a ~$130 kit, struggled with tolerances, wasted filament, and eventually cracked the code on designing parts that actually fit together and move. Now I teach other hobbyists how to do the same — without the months of frustration.
Engineering confidence, one mechanism at a time.
