      This is my first printer build and although it took me a year and a half, this printer is awesome. The Plastic Beast is a CoreXY printer and has a 440mm x 440mm x 440mm build area, and can print up to 600mm diagonally.

      The Printer consist of a frame built out of 2020 Aluminum Extrusion Metal, MKS Sbase V1.3 controller and TFT32 Touch Screen. It has an E3D V6 Hotend and a BLTouch for auto bed leveling. I also designed a series of cable concealment brackets to conceal all of the wires and make it look neater.

      I have included my Sketchup drawing, Bill of Materials, and a complete step by step tutorial with pictures. Every part on the drawing is 3D printable and ready for .stl export. This allows you to modify for your own equipment.

      1. The first step assembling the frame is to make each of the 4 square sections at each level. When assembling each one, pay attention to the direction of corners. See the pictures below for reference. When tightening the screws, just get them snug at first because you’ll want to make sure the whole frame is square before you tighten them for good.

    Reason for this Build

    I built this printer to have a larger build platform, and better quality than my Prusa i3 clone. I posted this build and wrote the tutorial so people that don't understand, can have a good guide written in a way that anyone can understand.
