MOLLE-Compatible 1911 Magazine Holster (FLEX)

Attached are two MOLLE magazine holsters for single-stack, .45 1911 magazines. Both of them require a single column and two or three rows of PALS webbing to properly attach. They are intended to be printed out of TPU and hold your magazines with friction without marring them or requiring any periodic adjustments. I have tried them with USGI-spec magazines and the factory magazines for a Remington R1 Enhanced (basically USGI) and found the fit to be tight enough that I don't worry about them falling out, but loose enough that I can easily retrieve them.

I've already taken one hiking with me (and dropped one with a magazine in it). The extra “bulk” protected the magazine from me clumsily bumping into things, and nothing was dislodged or fell out when I dropped it. Overall it seems like a durable, east-to-print design that will serve its intended purpose of surviving wilderness outings and three-gun competitions.

I have printed the double-magazine holster and can confirm that two Check-Mate magazines (USGI spec with a bigger base) fit without interfering with each other. I'd recommend attaching them with metal MOLLE sticks; there are printable ones on this site but I will not recommend any as I have not tried them.

The text on them, while well-intentioned, looks bad if your filament is even a little translucent. I plan to remove it in the future but it doesn't affect functionality at all.

Print Settings:

Printer: Prusa Mk4S, Prusa XL

Material: TPU (I use Overture high-speed TPU)

Temperature/Speed/Etc.: AmazonBasics TPU defaults from PrusaSlicer (under FLEX).

Infill: 30%. Infill can affect the “fit” of the magazine: at 50% I struggle to remove it, at 15% it doesn't feel like it holds it very tightly. Feel free to experiment and, if the fit's too tight, run the magazine in and out a few times to loosen the holster up a bit.

Supports: I used snug supports everywhere to prevent issues with the MOLLE attachment points. If you're confident in your bridging settings you may not need them. I've found supports to be easy to remove with when using TPU so I don't shy away from them.

INTENDED USE CASE:

As stated above I intended for these to be used on .45 magazines. I do not have any experience with 9mm or 10mm 1911s, nor do I have experience with 1911s chambered in more exotic calibers. As such, I cannot guarantee anything else will fit properly. They WILL NOT fit any double-stack magazines.

They're dimensioned to hold the standard seven-round magazine; larger-capacity magazines will be just fine - you'll just have more to grab on to when you need one.

These are intended to retain the magazine(s) via friction. Therefore, printing them out of anything other than a flexible material is ALMOST CERTAINLY A BAD IDEA. They squeeze the magazine fairly tightly when printed out of TPU and therefore I'm fairly certain that your magazines will either not fit, or not come out easily, if you print them out of anything else. Feel free to try (and let me know if it works), but my intent when designing them was to use TPU.
