These are 3d printable handgun frames compatible with gen3 Glock 17/19/26 parts. They were created by combining the ergonomic shapes from my PP43X Organica design with the gen3 dies from my Glock build kit. The Organica models are somewhat unusual in that there are virtually no flat exterior surfaces, save for the accessory rail. I designed them to maximize comfort in my (extremely average sized) hands, and hopefully you will find they fit yours as well. Included are 17, 19, and 26X frames in a small selection of different grip patterns. The 26X is a frame with G26 geometry, but with a G19 length grip. Glock does not make a 26X, but if it did this is what they would name such a gun. The dies are derived from the corresponding FMDA models, so assembly instructions for the FMDA frames apply (and are included). They use gen5 slide lock springs, because gen3 springs do not play well when printing rails down (as you ALWAYS should). There are more than plenty FMDA derived models floating around, but very few (pretty much none) for left handers, so to equalize the balance just a little, this release includes only left handed STL's. The STEP file includes both left and right handed unadorned versions. -PP (twtr: @phil_phisher)
