This is the 3rd design in the Buster Beagle 3D injection molding machine series. This build increased the shot volume to 3 cubic inches and incorporated a pneumatic cylinder to provide the pressure for the shots. See below for links to the full BOM as well as PDF plans for how to make your own.

This is a DIY build and is not sold as a complete kit. This build deals with heat, pressure, and electrical power so do proceed with caution and build one at your own risk. Always be careful and keep hands free of heated components and moving parts. Only work with electrical components if you feel comfortable doing so.
