\r\nIn March, 3Demon Studio 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

\r\nThere is something strangely satisfying about marble runs, no matter how old you are. You drop a marble at the top and watch it roll, turn, and finally reach the end. For this Flash Contest, design a 3D printable marble run that makes that little journey fun to watch. It can be a simple track, a set of ramps, a spiral, a funnel, or a small modular system. You only have 17 days, so there is no need to overcomplicate it. But if you want to add a switch, a moving part, a themed element, or make good use of tree supports as part of the look, go for it. As long as the marble gets from start to finish and people want to try it again, you\u2019re on the right track.\r\n

\r\nSpring evenings are moving outside. To the gardens, balconies, terraces, and open windows. And for this flash contest, we want to see your take on wind chimes: something that moves in the breeze, makes sound, and... looks cute. Think about how the parts are suspended, how they hit each other, and how they catch the wind. It does not have to sound like a concert instrument, but it should be printable, hangable, easy to assemble, and interesting when the air starts moving.\r\n
