GAU-8 Gatling Barrel (A10 Warthog)

This is a pen holder modeled after the A10 Warthog's GAU-8 Gatling gun. Measurements were carefully taken to be as dimensionally accurate as possible to the real thing. It's able to spin freely on a ball bearing shaft.

Be sure to only use supports for plate #1 (Barrels/Heat Shield) - threads on other plates will print fine without support. Its also recommended to increase wall count to 3 for the shaft.

A single 608 2RS (8mm x 22mm x 7mm) ball bearing is needed. It should press fit under the barrels. The shaft should also fit snug into the bearing - this part was made separate from the base for test prints (or easily replaceable if broken). If you run into fitment issues, increase or decrease the size of the entire shaft model by increments of 0.5% on the slicer until desired fitment is achieved - there is enough tolerance on the threads to accommodate for this.

If you can manage cleaner hole cutouts on the heat shield, please share your print profiles!
