\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

\r\n\r\n## The first designer challenge: modular drawer system\r\n\r\nYour system should let users build their own setup from separate drawer modules.\r\n\r\nThe design can include stackable drawers, side-by-side connections, pegboard mounts, desk attachments, or extra add-ons that can be printed later. Different drawer sizes, label holders, interchangeable parts, mounting options, and expansion pieces are all welcome.\r\n\r\nYou can also experiment with the opening mechanism. A simple handle works, as does a sliding latch, a push-push lock, or another solution.\r\n\r\nThe important part is that the design stays modular and expandable. Users should be able to adapt it to their own workspace.\r\n\r\n
