Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4801977.

This is a Beretta Nano BU9 Speed Loader This is a remix of https://www.thingiverse.com/thing:4780910 . It is a bit different than the Ruger model referenced here. It has a groove cut into it to accommodate the small nub on the side of the Beretta magazine that is not present on other single stack 9mm pistol magazines I have worked with. This has the Beretta logo and model on the side of it (even though my picture barely shows it)

I have added a video to show how it works
