D.Va Cruiser light gun replica from overwatch.3d-model designed in Fusion360 by me and may not be a 100% accurate, but I've designed and scaled it the best I can manage.Printed version on the photo represents the model in full, printed at .15 layer heightThere is a solid model you can cut in half length-wise for 3d-printing.

UPD(08.16.2018): Added a cut in half version you can add lights to.There are now three additional models you can print flat and easily add lights to your prop.
That version contains cutouts to insert a battery pack and lights of your choice (LEDs, LED strip, etc), and there are precut channels for the wiring. Handle bottom is separate, you can glue it on or add magnets to have access to the power source.
