3D printers are a common tool in many STEM disciplines. They allow for complex rapid prototyping and testing on many types of materials. This project shows how they move around on an x y z movement can can reach any point on the bed. Worm gear elements are used to create a leadscrew that can drive the main beam up and down. This build only contains 250 parts, making it a great desktop addition for any stem teacher, engineer, or DIY enthusiast.
I hope this project helps people learn how these printers work and move.
