Just a quick flick changes this from a thumbs-up to f*ck you. Use it as an ornament, refrigerator magnet, make it into a wearable pin, or just leave it out as a coffee table curio.
This design uses 3mm (1/8") thick material.
The finished assembly is 3.3"[84mm] wide, .6"[15mm] thick, and 3.3"[84mm] tall with the middle finger extended.
