drew bracket version 3.0

Now that the iOptron / GoToStar declination motor was unmounted, I was able to look closely at it. And that's when I realised, while a good facsimile, it was unique in a number of ways.

Grabbed the calipers and measured it! Clearly the dovetail was not as long. But I was a little surprised to find the dovetail shorter too. That meant the stock grub/set screw locations I had chosen in version 1.1 would not work right. Well, only one set would grab.

After a few experiments in 123D, I moved them back or aft. And down a bit.

From the bottom. Space for the bolt ridges clearly visible.

Sent the revised diagrams (in Imperial measurements this time) to Jeff. OK to go.
