Parametric IWB Doublestack Magazine Carrier

AuxArc presents a second attempt at a Parametric IWB Magazine Carrier.  This is a much more comfortable, albeit slightly larger version of the other one.  

  For my guys running doublestack handguns from concealment, either every day or for USPSA and IDPA, here's a IWB Magazine Carrier that can either be standalone or attached to your existing 3d printed holster.  The standard STL I've attached works well with my M&P and Walther PDP mags.  It will take a Glock mag but it's not happy about it and should be a little deeper.  Simply use the parametric customization tool to build your specific magazine carrier, download and separate into the individual pieces in your slicer.  Align and support as needed and print. You can download my 3mf to see how I have mine laid out and supported. All pieces are designed to need minimal supports, it's really just the hinge.

  If you're doing the standalone IWB setup, you'll need the carrier, the wing and two belt clips.  If attaching it to your holster, you'll need the link piece, and you can install it using filament in the hinge.  Be sure to mirror the carrier so you can match the hinge up to your holster correctly.

  This carrier uses #8-32 hardware specifically.  The recesses accept nylock #8-32 nuts and retain them.  

  More holsters and gear coming soon!  Comments, critiques, requests all welcome!  You can follow me on Youtube or on X!

UPDATE 5/24/2026:  Developed a new parametric carrier that can support thinner magazines and have and angle to it for specific use with Appendix Holsters.  Both options will be available.
