When I started 3D printing I kept wanting to experiment with what you could do which really influenced my designs at that time.

I made a swivel lid box, an organizer, and a trapped gear that walks along a gear track in the floor of the box.

I made translucent stacking cones that would look cool with a flashlight, a gear rack where the rows spun independently, and functioning gears that fit on my son's Duplo Lego's.

I also made slim fitting stacking cubes that you can mix colors and build with.
