A 3d model of Rimurus / Shizues mask from TenSura that I made for a commission on Etsy. It should print alright without supports if you dont mind the inside being a bit rough around the middle, at least my cr10s managed. Rimuru Lower and Upper are the mask cut in two for 3d printers that dont have at least a 230x182x80mm build volume.
To complete the mask just heat up a small red glass marble (around 10mm diameter) and press it into the groove in the middle. Alternatively the orb version has a small sphere there to be be painted.
