Cool model! I have long thought there should be a second use for all the calibration prints. If I may offer a suggestion: Make a version of the calibration cube with soft edges and corners, and alphabet letters. That way the second use could be children's blocks. I have a few other ideas if you are interested, msg me here on patreon.

The 5.1 Good profile (not the ExtraFast) is faster than this 5.2 profile. A model I'm printing shows 5 hr on the 5.1 while requiring 6hr 20m on the 5.2

Not sure how big the difference is in the quality, but saving 1hr 20 minutes might be worth it. So I'll stick with the 5.1 profile.

Thanks for offering these profiles. They've been a game changer for 3D printing newbies..

Thank you, CHEP!
