Back in May, I decided that it was time to upgrade to a larger 3D printer. The two obvious candidates were the Voron and the RatRig. After some deliberation, I decided on getting a RatRig V-Core 3.1 400. After having built the printer, it was time to test it. I landed on Droid Division’s incredible Battle Droid I have been meddling with 3D printing since Makerbot launched the Thing-O-Matic back in 2010.
