About this 3D model
My simple model of Thing, from The Addams Family. Features scars and stitches just like the real thing, with a large through hole for a keyring or a ball chain. As it is, the model loads at 50mm tall, but it can be scaled up or down depending on how big you want your Thing. I printed mine at the standard .2 layer height, but you can go .16 or .12 for that finer detail. PLA is fine with as little as 10% infill. I use a brim just for that extra adhesion while the fingers print.
