The original design is great, but it lacks articulated joints, as in another Mario model. I replaced the static connectors with rotatable ones. The joints, collar, and bracelets can spin freely. The tightness is tuned to have a good tolerance for scaled models. The original connectors are still available, but you don't need to print them.

I also organized the spikes, teeth, and fingernails to match better when assembling.

I used the polishing liquid as the glue for the cleanest finish.
