Quinn 48pc Impact Socket Organizer for Packout Slim Case
Here's my very basic solution for the quinn 48 piece impact set that was modified from user Balake from makerworld Milwaukee version. It'll fit 46 of the 48 pieces. The two larger extensions do not fit. It's not exactly a perfect fit due to some of the sockets putting pressure on the lid, but it definitely closes without risk of damaging your packout case.
edit 3/16/25: I had to reupload both parts due to some slight issues with sizing. adjusted, printed and its all good now.
Shout out to Balake and his hard work. Heres the original file I modified.
