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.
Living dangerously would mean that you print the same part 20 times at slightly different orientations, put them all in a bag and pick one at random for a structured part.
Any reason you didn’t print them lying down?
Only kinda sorta dangerous, I’m not leaning into chaos random. I’ll update the post with a better view of the final part. The two cylindrical recesses are the dimensionally important features and bridging would hurt that.
My guess would be that they need those shafts smooth, but if the outside is smooth it doesn’t matter as much?
