Thanks! Here is the thingiverse link www.thingiverse.com/thing:4779693, I’m not sure if I did this right because it’s a blank in the preview.
I have a creality ender 3, it’s cheap and works well. I plan on shipping off cards to get graded in these once I finish using them for transport (if ludkins is okay with that). They’ll fit inside the small size USPS fixed rate box.
Any chance you know what the dimensions are? Looks like the similar safes from Bunnings are mostly First Alert brand, which I can probably get in the States somewhere else. Don’t mean to bother, but this is like *exactly* the kind of thing I’ve been hunting for forever.
