Camera Lucida 4"x4"

I've seen other lucida designs but the mirror and glass sizes were always hard to find. This design is meant to use easily available 4"x4" mirror Candle holders and glass form a 4"x4" frame both from dollar tree. I used an old lamp stand to hold but included the step files to adjust the design to however you want to design. This design also includes a slot for standard 100x150mm photo filters to improve the contrast on the lucida.
