If you happen to remember from this earlier post, a kinky friend of mine told me about a guy on Etsy who was making custom gas mask canisters out of 3D printing. He brought up the good point that they could be good for putting in smelly socks or more, but did admit that the typical size fills it up so much, it can make breathing difficult.
So I ordered one myself, and asked for it to be light gray in color and 10cm long. I was sort of making a guess, but I was hoping for the best. Well, I think it worked! I’m able to stuff in one smelly sock and did not seem to have any trouble breathing (admittedly, I only had it on for about a minute to test it out–I haven’t had time to do more long term testing yet).
Also, at his request, I tried stuffing a smelly, used jock in there, and it fit as well. It took a bit of stuffing, but it did work with a bit of room to spare.
I think if I got another one, I’d maybe ask for 12cm to have the extra space. But I think the 10cm will work for me! And you can really smell things in it, so I’m sure I’ll find a lot of uses.

Top screwed open so you can see inside. Air holes at the bottom. 
Stuffed my rank Sk8trboi sock in there first. You can just make out the “Sniff me”. As you can see, there’s a bit of room at the top.

Another view. I actually had room to push it down a bit more, but I thought it looked sexy filled to the top.
I’m keeping the name of the guy confidential, because my friend and I both believe that he probably doesn’t realize we’re using this for kinky purposes, so we don’t want him scared off. Plus, I’m not even sure he’s still making them. So I’m glad I got mine when I did.
Although funny story… this item took me over a month to get, and not because it took him a long time to make… but because it initially got lost in the mail. Literally. Lost. It wasn’t his fault, but it was crazy I had to wait that long, especially when the guy is only about a 25 minute drive away from me.
