3D Modelling, 3D Printing Camera for Hama Bead “pictures” November 12, 2022 My kid started making Hama bead “pictures”, so I made him a camera! Design time was around 3 hours, and so was print @0.15mm. A very simple print but also very liked. What can I say? I love to make useless stuff, hahah. The ready result and the “pictures”. The pictures with to the back of the camera. The camera’s back is held in place by magnets. The hinges are magnetic as well. You can see the picture through the 43mm “lens”. Why 43mm? Well, that’s the focal length of a human eye.
