Many people before me have built R2D2 and other R2 units. I wanted a big 3D print project so I thought why not.
The printable R2D2 body that you see me making here was released by the wonderful Michael Baddeley over on Thingiverse.
I support Mr Baddeley on Patreon, check him out.
I'm also on Patreon and If you would like to support me you can do so here.
