This 3D print file is for supports designed for Ciano lights (in my case the 60L model but it also fits the other models). The file includes two support brackets and four screws. Print both support brackets at 100% scale. For the screws, print two at 90% scale and the other two at 100% scale. Supports are necessary, with tree supports being preferable. I printed mine with a 0.1 mm layer height; if you choose to print at 0.2 mm, do so at your own risk.
