Benelli .22 Empty-Chamber / Dry-Fire Plug

This is an "Empty Chamber Indicator" (ECI) plug for the Benelli MP90S and MP95E .22 target pistols. Depending on the exact vintage of your pistol, it can also be used as a dry fire device. This is largely copied from the factory plug, with a few modification to make it printable and a bit easier to insert into the chamber. If you can find one, the factory plugs can be expensive ( > $10). Once you have things set up, you can crank out a bunch of these for pennies.

In addition to an STL file, I've also provided a STEP file in case you decide you need to tweak the design.
