This Saitama figure should slice and 3d print using cura slicing. It stands roughly 12cm tall and since it is broken up into mutliple pieces, I believe most 3d printers will be able to make all of the parts. Splitting the figurine into multiple pieces will also reduce the amount of support material which can create un-wanted deformities. The cape section has built in support material because the cape is thin and the extra bits should be easily removable (don't mind the obvious weird pieces at the bottom, they are meant to break off).
Here is the history of how this came to be. I really liked MartialDesign's Saitama figurine, but I could not get a decent 3d print. The main issue (as commented on MartialDesign's Saitama page) is that it won't slice correctly using cura. The slicing problems occurs because the original design is hollow and has exceedingly thin walls which the cura slicer rounds to thicknesses of ZERO. I solved this original problem by filling in the hollow parts of MartialDesign's Saitama figure. This then lead to secondary problems. The cape in MartialDesign's Saitama is not hollow, but still has parts that where extremely thin. I ended up re-designing the cape so instead of being blown behind Saitama, it is now gently being blown behind him (which also removed the problem of how to remove support material from something that is really thin). Then I was so far in I ended up re-redesigning the hands to fists (I was literally breaking off Saitama's fingers with the tip of a paint brush).
