Yeah, I print pretty much exclusively in PETG, so I stuck with what I was familiar with. That was the one area I deviated from your standard recommendations. I did check a few measurements and everything fit together nicely, so I didn’t think there would be an issue. If I remember correctly, I upped the infill on some of your lower recommendations (parts at 45-50%), but stayed close to your recommendations at the higher infills.
That could be the problem though. Ugh…I’d hate to have to print everything again.
