These are a set of custom RX-64 brackets that I had machined by
Big Blue Saw.
They essentially are based upon the Bioloid set of brackets, including 45 degree angle brackets, long brackets, and wide brackets as well as the two variants of side brackets that attach to the servo body. I did not include any normal straight brackets (these can be purchased directly from Robotis), however if there is a request for them I could draw one up quite easily.
All of these are built around 2mm 5052 aluminum and require a brake to bend. These are built in a simplified manner compared to the standard Robotis brackets to keep machining cost down, but are more than sufficient for most purposes.
The included feet are an extra, something I designed for my own uses. They are not an easy part to have made, your machine shop will probably give you dirty looks if you bring this in looking to get it built.
If there is enough interest, we're entertaining the idea of having these manufacturer to sell in our store. Feel free to PM me if you would be interested.
