This is an original design made from scratch. This is Six G uns Autobot transformer that when paired with the can nons from my upcoming Metroplex design will transform into a tu rret and will go on a peg on Metroplex when in city mode. All parts were made on my fdm printers using PETG filament, but you can use PLA but I recommend only on parts that don't rub together constantly. Pegs are included to put together but on head plates you can use filament to hold in place to the chest part. Glue is not required but you may use some if needed. Also on ball joints, you might need to warm them up a bit to get them to lock in, and oil may be required because they are notorious for breaking off. If you have any questions please message me directly, and instructions are included.
