I really wanted a 3D printer at some point, but they were still really expensive!
Using some tweaked open source designs (specifically the Prusa i3 and Wilson), an Arduino microcontroller, and a used XBox 360 power supply, I built this open-frame printer for ~$230.
- single 3mm filament extruder with a 0.5mm nozzle
- 8” x 8” x 7” build volume
