osr2++

A smaller OSR2+ integration, you need to install the servos rotated.
I’ve beefed up the case and the arms to be printed with the cheapest PLA available.
The lid has provisions for a fan.
I added the 3’rd servo for pitch control directly on the base, so no extra parts are needed to get to the OSR+ level. There are provisions to attach the pitch arm directly for people that want to use only 2 servos.
The geometry for the pitch is a bit different, but as from the user experience it works similarly to the OSR2+.
Also I added an under-user support, the user sits on the support, providing stability to the whole mechanism.

The support uses an 1 inch aluminium pipe
