In the past few years, we have covered plenty of neat kaleidoscopes here. This 3D Printed Kaleidoscope by Charles Karadimos is quite special though. Its body is made with a 3D printer in about 15 hours. It also has 6 multi-layer fused glass cabochons inlaid on the body. As you rotate the chamber, you will be able to see beautiful 8-point images thanks to the 2-mirror system inside.
