Summary

What? Did you think that self-replicating 3D printers are fully grown when they are born?  

This made a great avatar for me on Thingiverse when I first started 3D printing with "MacGyvrBot" back in 2013.  

Instructions

Print two sets of baby bot parts using two different colors of ABS.

• Coat the parts with solvent* to make them strong, sand off flanges and rough spots, then coat again and sand again.
• Make sure all the parts fit together, then assemble two-colored baby bots and solvent-bond the parts.
• Sand again to make smooth joints and coat with solvent again for a glossy finish.
• Drill tiny holes and use pieces of extruded filament to go from the spool to the extruder.

*WARNING:

• -Use CAUTION during solvent bonding!
• -Use solvent with MEK (methyl ethyl keytone) such as Oatey cleaner (yellow label white can) made for ABS plumbing pipe (or use acetone or superglue).
• -Work in well-ventilated area.
• -Use eye protection.
• -The solvent dissolves many things, and the wet plastic stains whatever it touches!
• -Use latex NOT vinyl gloves!
• -Use aluminum foil on work surface!
• -The solvent can also be used to heal delaminated parts, but BE CAREFUL!
