I'm working on a set of "armour" to make Bittle look like Transformers Ravage. Initially I wanted to replace all of Bittle's parts, but I was unable to disassemble the legs, and I'm not sure the main body can be disassembled without risk of breaking, so I built around the legs using the leg clip that I posted earlier, and I'll just repaint the body. So far each part is taking one day to engineer and model. Do the elbow servos need much ventilation? My replacement forearms cover the sides of the servo completely, only the top and bottom are open. I plan on only carrying it on my shoulder to a comic con and having it do light animations for an hour. The model files will be for sale in a month or two, but I will also share some parts for free on Printables.com, like the paws.

I have uploaded the 3D model of the neck servo attachment to my Printables account, along with a remodeled version of the paws, that fit Bittle's original legs. https://www.printables.com/@DonPatrick_1489999/models I hope they will be of use to someone :)
Finished! And it turns out that Bittle is in good scale with Robosen's Transformer robots. Sorry about the blurry video, I only just found out that my camera's "fixed focus" setting is rubbish.
The complete 3D printable kit is up for purchase on Cults3D. I'll send Petoi a free copy. https://cults3d.com/en/3d-model/gadget/robot-jaguar-kit-for-robot-dog-bittle-based-on-transformers-ravage
Now I'll work on adapting the paws to Bittle's standard legs and some other parts that I'll share for free.
Largely finished now. I just want to remodel the back cover, which is currently just glued onto Bittle's original cover. I had to redo part of the neck, because I put the neck's servo too close and I couldn't replace the battery without half disassembling it.
Cool!👍
BTW, nice blue hobby pad. Where did you get it?
Looks like Bittle has been hitting the gym - love it!
