First try. I’m running klipper with z calibration with a bed mesh, so my first layers are very consistent.

I manually painted the trees in two locations. The first was below the cylinder cutouts even start to give the print a touch more stability, but I probably could have gotten away without them. The second was for the small overhang at the top of the cylinder. This is ASA, which tends to sag on overhangs a bit more than PLA. A bevel would have been a great way to eliminate the need for the second set of trees.

The prints are the middle section of a rebar clamp for my garden. I’ll try to post a photo of the completed unit in a day or two. So not a jig per say, but functionally very similar. Good eye!
