Update: This was designed for an original Ender3, if you have a newer printer like something from BambuLabs you will need to expand XY by 0.1mm (X-Y contour = 0.1) and elephant foot compensation = 0.0.
Just played some Minecraft Legends and wanted to make a Piglin model. This one fully articulates and is print in place with built in supports. You will have to take a cutting tool or blade to the joints that move, to free them up and remove the built in supports.
Test printed on an Ender 3 with a 0.6 nozzle, 0.2 layer height, 4 walls, 4 top layers, and 3 bottom, at 30mm/s. The supports between the head/chest and chest/legs is 0.2 in height with 0.2 air gaps, with softer PLA it will scrap off easily. The arms take a little bit of patience to free up and start rotating, and with softer PLA there is a risk of twisting them off, so take some time. Included a sectional image of the joints to make it easier to see where to apply a blade to. Some paint or hot glue can add more friction to the joints.
Good luck and will add more or update model with requests.
Update 4/20: added more clearance to the arm joints, made the feet larger, added leg clearance and made earrings larger. Model can be laid on it's side after the head is freed and by pressing or tapping on the shoulder the joint can be freed up in the socket.
The author marked this model as their own original creation.
