The build plate holder can hold various size build plates. I used Area 51on Printables design and enlarged it to ensure the plate slots will hold thicker and larger plates. I combined it with a base designed so it would have a wider stable base. The base also has a wire tunnel to enable you to mount a personalized sign in the front. My sign was designed by Maaght. The blank face plate from his design was also enlarged to 183mm to ensure it was large enough to not fall through.
