Extension for Prodigy (and other 2011?) factory basepads

I like all of my magazines to be the same length when on my belt so I created these extensions.

The “lock” replaces the factory part and accepts a #5 x 5/8" screw.

There is no additional capacity added to the magazine, just an increase in overall length.

The extensions in my photos were printed in PETG at 0.3mm layer height, 4 perimeters, 15% gyroid infill and with 0 bottom layers in order to get the infill patter on the bottom of the extension.

I added fuzzy skin in PrusaSlicer with the "Smart fill" tool with a 3 degree angle and selected three locations on the “base” part to improve grip. 

Moving the seams to the rear improved the overall quality of the printed parts.

Use supports for the “lock” part.
