Mr. Bendy Quite Contrary How Does Your Lumbar Flow

thingiverse

A lifting demonstration model I saw on one of the FB groups. It's a work in progress and I don't have my printer with me so unfortunately I cannot test how well the pieces fit together. Based on joint simulations however, it should be ok. I am not sure what the actual model uses, but you will need to pass a length of elastic through the ventral neck hole, run it down through the lumbar pieces, round the pelvis, and up through the lumbar pieces again, and out through the dorsal neck hole. Tie it off in a knot to keep it in place at either end. All jointing holes are m3 exact, give them a little drill out. Ideally you should place a washer between all joints. Maybe a nylon washer? Haven't really tried those so that would be interesting. Planned modifications: 1. Create some keying for the lumbar pieces so that they align and stay aligned. At this moment they are flat pieces so although they should stay aligned when the elastic is taut, I want a more certain way of keeping them in place.
