Very nice model. Boosted. I created a 4 color version for ams. I can upload the file if you'd like. Filaments used: -SUNLU Glow in the dark green -eSUN High Speed PLA+ Brown -eSUN High Speed PLA+ Grey -eSUN High Speed PLA+ Black Printed on A1 I did have an issue where the nozzle was hitting the model causing the base of the gun to pop off the bed. I turned on "z hop when retract" and set the distance to 0.6mm and increased the brim to 10mm. I also unchecked the "reduce infill retraction". Doing that allowed me to get pretty clean prints.
