This hand sanitizer holster/case is useful for carrying hand sanitizer by clipping it to the outside of a backpack, a belt, keychain, etc. I designed this earlier during the pandemic, inspired by a design by wskyler on Thingiverse, but consisting of a fully original CAD and design. This improves upon the original by adding holes on either side so hand sanitizer can be squished out of the bottle without removing it from the holster, and additional designs are made for different size round and octagonal bottles.
Edit: This design is now available on Thingiverse.
