\r\nShoes are one of those everyday things that are easy to improve with a small 3D print. For this flash contest, design a practical or decorative shoe-related accessory: something that makes shoes easier to wear, store, customize, or repair.\r\nYour model can be a no-lace system, lace decorations, a shoe horn, boot hook, heel protector, drying stand, or any other helper for footwear. It can be simple, but it should solve a real problem or add something useful (or cool). A tiny print that saves time in the morning is just as welcome as a storage system for the hallway. If your model works best with flexible filament, PETG, or a specific print setup, don\u2019t forget to mention it in the description.\r\n

\r\nIn March, designers from 3Demon created a set of great-looking skins for the CORE One L, turning the printer into three very different things: a TARDIS, a dark steampunk machine, and a small mushroom forest scene. We liked the idea a lot. The CORE One printers have a clean, compact shape, and they feel like a perfect base for more decorations, add-ons, and mods - something that can take on a life of its own in the hands of the Printables community.\r\n
\r\n
\r\nDesign a printable look for the CORE One+ or CORE One L: decorative covers, themed panels, magnetic accessories, frame add-ons, button covers, small props, or a full transformation of the printer into something completely different. It can be sci-fi, fantasy, industrial, cute, minimal, strange, practical, or something out of this world.\r\n
\r\nYou can use the CORE One and CORE One L CAD files released under our new [Open Community License 1.0.](https://blog.prusa3d.com/core-one-cad-files-release-under-the-new-open-community-license-ocl_127290/). Simply load the files into your preferred 3D modeling software and build around the printer model!\r\n\r\n#### We have just one important rule: \r\nmake sure the design does not limit the printer\u2019s functionality. The door must still open properly, controls should remain accessible, and nothing should interfere with printing or ventilation. Take the CORE One and give it a character others can print, remix, and build on.\r\n\r\nRead more info in our article! Just hit the button \"Entry info\".\r\n
