Ottto - The Taller Otto

If you are following from the original [Otto](https://www.thingiverse.com/thing:1568652) , you just need to print the OtttoDIY_body_V9.stl. --- Follow-up from the original [Otto](https://www.thingiverse.com/thing:1568652) . I have a problem where my Otto couldn't be driven with 4 AA alkaline batteries like it is mentioned in the Otto's DIY manual. Not really sure how the situation is in other countries, but in Indonesia AA alkaline battery has fluctuates current draw from 0.5 A to 1 A. A SG90 servo needs 220 mA, so four SG90s means I need at least 880 mA if all Otto's limbs are moving. The problem can simply be solved with adding another 4 AA alkaline batteries in parallel. But then, Otto need a longer body. Here, I made Ottto (it basically just Otto with the longer body lol). I made the body longer and added side inner-walls to keep the batteries boxes in place. You can place the batteries boxes with the cables facing upward (like in the photo) or sideward. There is a modular alternative here too ---> [https://www.thingiverse.com/thing:4549794](https://www.thingiverse.com/thing:4549794) . I just saw this after I done my Ottto. This alternative looks good, but without the side inner-walls.
