On my Franken9 build the catch cutout on my Sten mags is too low for the original magazine catch to engage. This revised mag catch allows the tab to sit lower in the magwell where it correctly engages the magazines I tested. Print vertically (file is in the correct orientation) with the front on the build plate, same settings as other Franken9 parts. Note that this design has built-in supports to give it more build plate surface, but an additional 5mm brim is recommended. Simply break off the front "corner" supports after printing.
I'm providing this as a STEP file to make it easy to adjust the magazine catch "tab" up or down slightly as needed for your build. All modern slicers can print STEP files directly -- just load it as you would an STL file.
