@A2: The relationship between the screw spacing, arm length, hub offset, and shoulder offset is complex. If you want to increase the xy then you will probably increase each of these a little.
The holes on the top are a hand hold. You can easily put a book on top of them if you want a heated chamber. (I print in PLA only so this is not something I choose to focus on. I am sure people will come up with all sorts of solutions.)
The bearings will be 1607s. They are about $10 more for what I need.
