Work in progress but figured I would share, there is no extension plate for the 22 version that keeps the 10 round limit That I have found. This is designed long enough for my pinky to sit comfortably but your mileage may vary.
The connecting rod is a separate file in case you have trouble printing it or would rather use something else, the diameter of the hole is designed to be 4mm with a length of about 15.90mm.
I also included the spring holder the sits at the bottom of the magazine in case you snap yours like I did... print that sideways with support under the cylinder.
Attach main part to magazine first then attach the secondary piece and insert rod.
