Nice. How does it run? What materials did you use?
Haven’t fired it (with the 16 inch barrel) yet, but plan to get some range time soon. Everything but the butt printed in gst3d PLA+, the butt is some no-name brand TPU.
Its a shame about gst3d no longer shipping filament, gonna make it difficult to color match if/when a part breaks.
UZI barrels are about 1/4mm larger in diameter than “stock” barrel. You only need to modify the inter diameter of the screw collar and everything fits perfectly.

The rifle configuration parts were printed on a Bambu Labs P1P, but the pistol/original parts (not pictured) were printed on an Ender 3. The pistol/ender printed parts had some minor warping issues, but it didn’t seem to affect the gun’s performance. The warping was only on the external edges, so it only affected aesthetics.
When my ender was my main printer, I had less success printing with PETG (sticking to nozzle instead of bed, more warping, sticking too well to painters tape and integrating the tape with the print). Try putting an enclosure over the printer or putting it in a small room, the ambient temperature increase should lower the chance of warping. I’ve found that cleaning the bed while it’s hot with alcohol works a bit better than when its cold.
PETG is a great filament if you can get it working, my only complaint is that the printer needs to be tuned more precisely than with PLA (bed level that works for PLA might not work for PETG).
