meArm Improved Base with Rails

When I printed the meArm, I noticed that the base really was not sturdy enough to support operations.

So I added rails on both sides for structural stability of the base. I fitted the rails with large round feet to which you can attach Micro Suction discs for great stability of the meArm.

While I was at it, I added correct holes and spacers to mount a RPI 3 in the back. Note that to give sufficient clearance for a PWM Controller HAT, increased the length of the screws mounting the rotation platform to the base.

Those suction discs suck hard:) So if you want to remove the meArm, do NOT pull it. Twist instead to break the suction.

BOM:

- 6 2x8mm screws
- 6 2mm nuts
- Optional 2 3x12mm screws to secure the RPI to the base (using the spacers)

If you strip the holes for Mounting the RPI, simply insert a little extruded filament thread into the hole (or use nuts) :)
