It’s a two part 3D print, with both parts the same. There’s a small amount of support material required for the dovetail joint, which is a bit tricky to pick out, but my objective was for minimum waste, which I think I achieved.
I had one printed today, the first one w/o supports so the dove-tails aren’t tight, but it worked fine anyway. Second one wasn’t done when I left for the day. However, I intend to just drill a few holes in the cross bars and screw it down to a piece of plywood as a bit changing stand. I’ll post a pic when I’m back on site.
With that in mind, if you added 2 holes and countersunk heads in the cross piece it could be used stand-alone, or screwed to the bench/etc.
