This is a rework of dcm7055's speedloader
For the glock .45 caliber mags
I printed at .35 infill and it works fine. I would probably recommend a .5 infill as the plunger does seem a little weak at .35
I added a small support wall to the front just to keep your lines straight as I know some 3d printers do not do unsupported overhangs well
