I was a Mobile Gun System platoon leader for a little over a year. I loved every minute of it and wanted to create a model to remember my time with the platoon by. Surprisingly, I wasn't able to find a single one. This one was built from scratch based off of google image searches, 3d game models, and my own memory. I wasn't able to get the barrel to print out right in .4mm layers. It looks better in .1mm layers, but is still incredibly fragile. So I just heated up a paperclip I with a lighter and stuck it in to the plastic of the turret. When the plastic cooled it compressed around the metal, and now its good and stuck! Any comments or recommendations for improvement are much appreciated.
.4mm print layer with a 50% honeycomb fill. It took my Printrbot Simple about an hour and 5 meters of filament to complete. Once it's done peel it off and get a good pair of scissors to cut away the base and support struts.
