About this 3D model

So how i do it i print so that my dice so that it can fit on the square. These fit curently 20mm dice. i spray mold realease before putting down the silicone make suure to use puddy to hold dice down so that it doesnt move . nice and easy to do instead of legos. this is the foggy piece with the bottom. if having any problems contact dallascourt7@gmail.com
