In my opinion, this is the easiest and most complete tutorial to walk you through building a large platform 3D printer and the Sketchup File is included for you to make any changes needed.. The Plastic Beast is a CoreXY Printer with a build platform of 440mm square. You can print 600mm or about 23 inches diagonal. Any level of user from novice to expert should gain something from my tutorial.

Vacuum Former built with off-the-shelf parts, works perfectly every time!
