I honestly didn't know I needed one of these until I found this. After printing this and putting it to use, I realized I had been keeping pouches in that I was done with until I got to a trash can. Awesome idea. I printed the profile as is, with bambu PETG HF and it turned out great.

Tolerances could be a hair looser. The Super lube ALMOST doesn't fit. But with that said, I printed the profile AS IS and it works just fine.
