Beskrivelse

Based on Articulated Shark, Happy Flexi Fish Toy Multicolor 3MF, Singlecolor STL ( https://www.thingiverse.com/thing:6729095 ) I found some small lasers on amazon[1] and immediately thought of sharks with laser beams. I modified the original shark to fit the small pcb with mounts for a pair of coin cell batteries (LR44) and momentary switch. The kicad project (the .zip file) is attached. Pcbway can fab the pcb (and I think they can also populate the board if you don't want to do the soldering yourself.. but in my case I already had the components so I soldered it myself). There are other places online that can fab pcb's but pay attention to the minimum dimensions available. Of note, kicad can export stl model of the board (if all the components used have a 3d model in your component library), I used this with some early test prints before I got the pcb's back, and while I was still playing with how the pcb fits into the shark, location of switch, etc. I've attached the .stl and also .3mf for reference. When printing, you need supports for the cavity the pcb fits in, but not the rest of the shark. Original (non-tree) supports work out better, IMO, for flat surfaces that are not on the print plate. I'd recommend split object to parts, and then move the plunger for the switch away from the rest of the model. (And then merge it all back together and use variable layer height for a better result.) The tolerances are tight for the pcb to snap in, so it isn't falling out and fits snugly to the switch plunger. You might want to do a test print to check fit when you get the pcb back and assembled. (Split object to parts in slicer, and delete the unneeded parts of the shark to save some filament.) [1] https://www.amazon.com/dp/B0B619MH7G
