10/22 Thumb Saver

10/22 Thumb Saver/Loader. 3 Sizes, with the ring inside diameter being 1", .8", and .6". It's definitely not a speed loader, but I can load a 10/22 magazine faster with it than without. This is used to press down all the other rounds at the back of the magazine before easily slipping a new round into the magazine. I've only used it with box magazines, but it should work with any magazine. It's supposed to fit on the left thumb, so let me know if other sizes are needed. I printed it in PLA, so I think any material (excluding flexible materials) would work for this design. Design works, but I might make some changes if I find a better design fit.

Update:So after a bit of tinkering, I decided to add a few different ends on them, and combine those ends all into one ring. I think I like this design the most, and they all feel a bit different, so you'll have a variety to choose from. I still like the circular end the most, but everyone has different tastes.
