I had an Etsy store order come in and I just couldn’t get one of my slime counters to print properly. Tried everything; adjusting layer height, slower print speed, re-leveled the print bed.
Turns out one of my Z-axis shafts had worked its way loose, which made the platform wobble during the print. A little bolt tightening and I was good to go, but not until I’d already made a dozen or so failed slime counters.
The original slime counter is here, free to download.
