RoboMorphs! are easy-to-print robot action figures that you can assemble, disassemble, and reassemble any way you want. Kwak (along with the other RoboMorphs) is being printed for our upcoming event at MOHAI. If you're in the Seattle area on the 10th of September (2016), drop by and build a robot!
If you want individual parts, go to the growing RoboMorphs! parts compendium, which we'll update as we post new RoboMorphs. You can find the original TinkerCAD file here. Let us know if you make a remix, we might add it to the compendium!
