Mini DVD Motor 3D Printer

Mini DVD Motor 3D Printer (V2.0) Inspired and based on the original mini DVD motor printer, by MegaAndy (which seems to be gone now?). However, most of the original has been changed.Improvements made upon the original:Everything is now integrated into one base, cooling fan, extruder, spool holder, etc. Entire printer fits in the palm of your hand while printing.All axis feature real bushings to reduce slop and increase print quality and reliability. Optional Dual Z axis. (Thank you to Icesythe7 for that idea!)Optional Raspberry Pi Mounts for either Pi 0 or Pi 2,3,4 for OctoPrint server.Utilizes a creality style hotend for greatly reduced weight (almost half vs V6 style)Parts required 3x CD Drive stepper motors OR 4x if going optional DualZ (highly suggested) This gets tricky because some of them have different hole spacing. I have noticed LG or LITE-ON drives seem to have the correct ones.12x 3mm ID 5mm OD bushings - Link here: https://www.amazon.com/Acoeitl-Bushing-Bearing-Friction-To
