I designed this when I was asked for a way to keep Narcan in a purse without worrying about it getting crushed. There's also a version with belt clips if you prefer that. I do recommend using a bright color if it's going to be in a bag or something like that to make it easier to find

I printed mine out of PETG so I wouldn't have to worry about them deforming in heat as I live in a hot environment. They would probably also work out of PLA, but I haven't tried that. The black one in the photos is printed with Bambu's PETG-CF

If you want to have the label you can print the label and glue it on. I designed it to be separate to reduce the number of filament changes. I also enabled ironing for the labels to look better.
If you don't want to I also include No Label versions that doesn't have the indent for the label.

The belt clips are designed to be held on with a M3x16 bolt and nut. The nut fits into the clip it self. You could probably also glue them on if you prefer.

I use STP files, but I ran them through an online converted to make them into STLs so if there's any problems with the STLs please let me know.

Supports could be good on the bottom finger opening the rest shouldn't require it. Even those are somewhat optional, it'll print either way but a little messy without supports
