Changes are cosmetic only. Uses a standard T4 hardware kit with screws in all the same places.
Not included are any unchanged parts, so you'll need to grab bits like the trigger, plunger, etc., from the original file set. https://www.thingiverse.com/thing:5163389
Not designed for easy printability. I made this for myself and just went with whatever I thought looked best. Support will be needed, and you'll have to decide orientations on your own.
Feedback welcome, though.
