\r\nWe\u2019re staying with the summer theme for one more flash contest. This time, we\u2019re focusing on baseball caps: simple summer gear with plenty of room for small 3D printed upgrades.\r\n\r\nDesign a 3D printable add-on, fix, holder, or decoration for a cap. It can help with storage, adjust the fit, modify the brim, extend the back strap, or add something unnecessary (like a tiny propeller). \r\n\r\nKeep it printable, wearable, and clear about what type of cap it fits. If your model needs a something specific like a flexible filament, magnets, clips, or something else, mention it in the description.\r\n
