About this 3D model

I made this a couple of years back, with no real sense of scale (forgive me). I plan on getting a 3D printer soon, which will allow me to make a test print. If you decide to print it, I would recommend scaling everything up to 160%. I have a version with a completely flat top and another with the chessboard grid made evident (named Indented Version). If you do decide to print this, let me know how it goes. Thanks and have a wonderful day!
