The most famous R2 unit from Industrial Automaton:
The title say "MOD" because both the dome and front panel are indentical to stock 30611 - the rest is all new.
When I started this, my goal was to simply replace the legs - they were the weakest part of the original set - and it snowballed from there.
The middle foot is now retractable and extendable because of the Technic T-piece.
A frontal shot with middle leg retracted. The binocs mimic the cabling R2D2 has at the bottom of the side "feet".
Back view with leg collapsed - due to space constraints, there's no back "cover", but the retracted leg mimics the port that R2 has in that are quite well, I think.
Thanks for watching.
