This is a simple design for a 1022 magazine lloader with a non-focus group tested name. This version works pretty well, as long as you keep it rotated backwards, against the spring stop as the rounds initially feed down. If you don't do this, it will double feed and jam. It takes a little practice to feel and rock the handle back as you load. The hopper is designed to accept what I think is a standard size CCI .22lr ammo box lid, if you want to have a clear lid.
The test print used less than 200 grams of PLA+ with a .2mm layer height, 4 walls, 12% cubic infill and tree support everywhere using a brim.
There are also several styles of "stuffer", that i made but have not fully tested. They are experiments to see if one is better, not iterative improvements. I do not recommend this for the stock rotary magazines, it isn't great but that may be because they are very tight in the base. Worst case though, you will have to print another rotostuffer.
(You will need an hour of careful sanding to smooth out the hopper center feed groove and use some common sense where to scrape and smooth. The hopper floor plate is probably the most annoying fitting job, but I didn't want it loose.)
You will also need:
2 - 3mmx16mm screws w/nuts
3 - 3mmx@25mm? screws with nuts
