Introduction: Lego 3D Printer 3.0
A few months ago I've built the 2nd version of my Lego 3D Printer, and today I'm going to show how to build the 3rd version.
Step 1: Watch the Demonstration Video (optional)
Step 2: What You'll Need (for the X and Y Axis)
Don't forget the Lego doors for equilibrium
Step 9: What You'll Need (for the Z Axis)
Step 12: What You'll Need (for the Extruder)
Step 13: Don't Forget the Gluegun AND the Paper Clip
Step 14: The Extruder Should Look Something Like This
Bend the paper clip in a way that it partially stuffs the hole of the gluegun nozzle. This will allow for a more controlled extrusion process.
Step 17: Voilà
Step 18: Tipp
Use elastic bands to strap the paper (on which you'll print) to the moving platform
