Since .22WRF is a lot harder to find and quite a bit more expensive than other .22 ammo, I decided to make it so my Winchester 1890 chambered in .22WRF can also shoot both .22lr and .22 shorts. These are spacers that go into the back of the carrier allowing it to carry either type of ammo without getting stuck on the next bullet. The long spacer is for .22 shorts and the short one is for .22lr. All you have to do is print the pieces, sand them down ever so slightly while keeping a tight fit, then stick them into the carrier making sure the notch is properly aligned. It'll be pretty obvious how it should be inserted. The pictures show what it'll look like. Have fun!

Print settings don't really matter, but 100% infill is probably better.
