Mazinger Z with movible arms

thingiverse

I created a revised version with movable arms by modifying it in Tinkercad. I'm no expert in making joints, so my idea may be rough around the edges, but it works surprisingly well. Reminders: 1- You might need to smooth out some parts on the arms and the hole in Mazinger's body using sandpaper. 2- I'm stumped as to why some parts got damaged when I imported the original STL file into Tinkercad - the helmet was ruined, but I managed to fix it, and the shoulders had a flat spot that showed up after printing, almost like it was part of the design.
