I’m happy with my 4XL, especially the XL part of it. I have printed tiny witches, they pop on a microswitch with a small LED in it. I use my Shapeoko for cutting out small rectangles of acrylic. I spraypaint them first with 2 layers of primer, followed by 3 layers of black paint. Then I engrave them and cut them out and pop them into the 3D printed cap. The light of the LED lights up the button text.
