Not my ammo, I hate guns.

I don't think the author tried to print it. Printed in PLA and except for corner lifting issues, it showed some other hiccups; Filets are not very printing-friendly, so chamfers would be better. AND the lid doesn't fit. It might be possible to hammer it, but the lip and the groove are definitely with a tolerance that would allow open/close the box (if it is not printed in TPU)
@mikrom hey, I’ve printed several of these since I modeled it a couple of years ago. Sounds like the difference in our settings wouldn’t have caused all of these issues, I haven’t had any issues so I’m not sure what it could be. Sorry that you had so many issues with it.
