This is a DIY mosquito repellent coil maker. Find your recipe, put it in the device, clamp it down and pull it out to dry(if need). You may need a release agent like a light oil or flour to keep your stuff from sticking to the lid side.
It is a large coil, so either center a smaller amount in it or scale it down.
Also, it is designed to have a pin made out of whatever you can find laying around to be put in the hinge. 1/4" bolt would prob work, but you may need to open the hole a little with a drill bit.
Also, I have added the sketchup file.

.2mm

I have not printed this, but I recommend .2mm height, 60mm/s and support for the top piece because the hinge hangs over. None needed for the bottom.
