Sandy2503- Doh! Forgot to hit publish…that should be fixed now.
One option for the pyramid may be to cut triangles out of thin wood, but then you’d be forming your own bezel…may become a much more difficult project. I’ve used makerspaces before I got my own 3d printer to easily print a lot of things, though since that was a 9 hour print for my printer that may be costly. I will have to investigate if shapeways can do it for a reasonable amount. I really wanted to make the project accessible to anyone, but a 3D model was really the easiest way for me to make the case! Thanks for the kind words, glad you all are liking my entry into this wild world of magic mirrors :D
