Re-posting since this didn't make it into the Ark content.
Re-Introducing my first contribution to FOSSCAD โ The Carrier Keeper. I've been a big watcher/consumer and felt inspired to contribute. I learned Solidworks and created a series of simple printable storage cases for an AR-15 BCG, 22-conversion BCG and Dedicated 22-lr BCG.
Firearm components often become dirty when used or gooey when cleaned and lubed. The Carrier Keeper provides a simple place to store a full bolt carrier group. It helps keep your range bag clean and your bolt-carrier group protected.
There are 3 files to allow you to choose your desired size and use case.

Often you have multiple bolt carrier groups (BCGs) some perform different functions.
For example, the lower BCG you see in the attached image is specifically designed to accept a completely different calibre bullet.
