That is interesting. I have never tried to route parts mid-print but maybe ill end up doing that at some point. I have printed most of the parts needed to make a press to insert heat-set inserts but have not had time to finish that project. Archive: https://archive.today/8Ehi2 From the post: >>You can hear sound, of course, but what if you could see it with a laser? That’s what [Goosetopherson] thought about, and thus a new project that you can see in the video below was born. The heart of the project is an I2S chip and an ESP32. Sound energy deforms a plastic film that causes a mirror to move. The moving mirror alters the course of the laser’s beam. An important part of the project is the 3D printed enclosure designed in Fusion. Some wires are routed through during printing, and there are heat-set inserts.
