The joys of parts with not friendly printing geometry. There’s another cylindrical recess running at 90 degrees to the one that’s visible in this photo.
Apologies for the very obvious layer lines. Harsh direct overhead lighting makes them a lot more obvious. The prints are much better in person, I promise.
Edit: Finished part showing the second cylindrical recess. They’re both dimensionally important, which is why the parts weren’t printed flat.
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!
