Well, I've started building R2-D2. I'm not sure how life size it will be, I only had letter sized paper on hand and scaled the printing to fit. I should add the caveat that this build (and therefore thread) may take a while. I'm the mom of an 11 year old with Autism and my time is not always my own, lol. With that said, here we go: I'm attempting this without the tabs; the removed tab is on the right and the attaching piece is on the left. I thought the best way was to mirror the removed tab so both sides were the same.
