Last year I switched to a Form 2 printer. The printer has a durable resin material that comes very close to PVC. This lets me print very sturdy action figures with great detail So I could finally start making figures in 3 3/4 inch scale. So I updated my caveman figure that previously was about 6 inches tall to the new scale. I made some slight changes to the clothes he is wearing as well as to the articulation. Most notably the ab-crunch joint.
