meArm Improved Bottom Plate with Bearing

Description

The meArm is awesome, but it has a major design flaw in that the entire arm essentially sits on the axis of the hip servo, which is just not very stable and puts a lot of strain on the servo. This improved base remedies these issues and securely sits the arm on a base with bearings. Instead of using commercial thrust bearings or balls, the bearings are actually incorporated into the mount plate and are printed. In order to improve the attachment of the servo to the mount plate, I also revised the mounting bracket to be more robust (use for the base and the hip and shoulder servos). To add some candy, I included some branded side panels as well:) The make the branding stick out, change filament at layer 30 (if printing 0.1mm)
