camplight is a little camping warning light with neopixels. it is powered by an ATtiny85, which can be powered by a li-po battery under the pcb. the camplight would be put together using glue and some double sided tape to attach the pcb to the case, as I can't think of a better way to do it.
the pcb files can be found in the pcb folder. it is made with kicad and you can get production files at pcb/production.
the case consists of 4 components which are the main base, the top, the button and an acrylic piece. you can find them in the models folder! (respectively, camplight-mainbase, camplight-topcover, camplight-button and camplight top cut.dxf for acrylic)
for some of them i got 100 because the total is cheaper
