Instructions

These are speed loaders designed specifically for some SIG and Ruger handguns. The manufacturer, model and caliber are shown in the file name. This design is sort of a knock-off of the design by jsteuben. I tried different "improvements" to his design but none of the improvements made it work much better except for tighter tolerances on the design. I beefed up some parts. These are designed for a specific magazine and other similar caliber magazines from other gun manufacturers may not work.

If you use one of these speed loaders, be safe! Also, the speed loader does not put a bullet in the magazine. You do. It's just a tool to save your fingers and thumb when loading magazines.

Operating instructions: Put your magazine in the speed loader. If you have a solid surface to work on, it's easier if you rest the bottom of the magazine on the work surface. Push the speed loader down and it will clear a path for the next bullet. You'll only be able to shove the bullet half way in. Then pull up the speed loader and push the bullet the rest of the way into the magazine. It really saves wear and tear on the fingers. I don't think it's faster than loading by hand, just easier.

There are some commercial speed loaders in Amazon and other stores. They have some advantages over this design.

If your semiautomatic handgun is not listed, follow these instructions to get one that will work (no guarantees):
1) pick the same caliber if possible; if not, pick a smaller one (if you have a 22, pick the file 22_SIG_speed_loader_ver8.stl, not the other one for the Mosquito)
2) flip the part on the build plate and print the bottom 1/4" of the speed loader.
3) check and see if your magazine will go through the small piece you just printed.
4) if it does, print the speed loader. There's a 95% chance it will work for you.
5) if the speed loader is too small, scale it up and redo steps 2 & 3. I would expect the scaling to be very small, maybe 101% to 104%.

Parts list: None.

Assembly instructions: None.

Printing instructions: Adhesion to the build plate is very important.

All of the speed loaders were printed on a Makerbor Replicator2

PLA (Makerbot filament)
Printed: Low(faster) resolution, 8% infill, 2 shells, 0.30 mm layer height, 230C

There was some minor tweaking of the design after printing but the changes should not affect printing the speed loaders.
