			*''To me, the last holes and big hole are too close.''

			You are right for most cases. There is a rare occasion when those small holes are used to bolt together multiple pivot plates while allowing a large shaft to be inserted, which may be useful under special circumstances. We can leave these for now, but will get more test data from our machines to see when these are useful. If they prove useless, we'll take them out or move the large hole farther out.

Start with the tubing file in sketchup, export to DXF for the one side - and basically draw the rest of the tube as a flat structure - so a rectangle with perforations for the 4 folds that will allow a flat cutout to be folded into a 4-sided tube. Once folded, the tube should be taped together, or a tab should be added so taping together is easy.		For non-flat files - such as tubing - this requires more work.
