Re-posting since this didn’t make it into the Ark content.
Re-Introducing my first contribution to FOSSCAD – 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.

Pretty common to have a standard AR-15 BCG and also carry a separate “Conversion” bolt that allows you to shoot 22lr rounds out of a 556/223 caliber rifle.
Oh I was thinking it was a .22 LR conversion not .223. That makes way more sense
