And the results are in.
The rectangular measurements are all very good. Even the 2 inch dimension is within 1 mil at the bottom and 3 mils at the top. All the shorter ones are within 1 mil. The only problem is with circles or hexagons on vertical faces where the top is lower than it should be. For example the top to bottom flat on the M3 nut hexagon should be 5.5mm but it is 5.33. The worst of the other two pairs is 5.47mm.
The problem is the initial unsupported span which seems to have drooped. I would not expect to see this where the holes/hexagons are laying in the XY plane.
Edit: In fact the holes in the top surface are all too small. The 0.24" for example is only 0.233". I don't have any imperial drill bits to try out so a future version with some metric holes like 3mm, 6mm and 10mm would be useful
Cheers
