Lithophane Lamp Frame -- Optimized for Minimal Frame Thickness

thingiverse

UPDATE LOG:\r\n2018-12-25: Enhanced spiral LED guides, elevated supports for the top pane, and enlarged holes in the lid for easier assembly. Included advanced renders.\r\n\r\nA lithophane employs backlighting to shine through a sheet of plastic where thicker areas of the plastic appear darker and thinner areas of the plastic appear lighter. The resulting effect is a glowing, black-and-white (grayscale) photo that "pops-out" of the plastic. It's truly breathtaking!\r\n\r\nThis lithophane lamp arranges 5 images in a cube that sits on a table and illuminates all sides simultaneously. It was inspired by the excellent work of Mafo [https://www.thingiverse.com/thing:1370792], I just had different design goals (as explained in the "How I Designed This" section, below).\r\n\r\nA few notes:\r\n* This lamp accepts five 100 mm × 100 mm × 3 mm lithophanes. It is optimized for lithophanes that have a 3 mm bezel around the edge.\r\n* This lamp has a post in the center upon which you can spiral an LED strip for illumination. For best results in illuminating the top panel, a little bit of soldering is required.\r\n* Since this lamp is designed for LED strip lights, heat production is not a significant concern.\r\n\r\n**Required materials:**\r\n* LED strip lights (I purchased mine for about USD$4 from ebay, though this was with 30-day shipping from China).\r\n* Power supply for LED strip lights (not all LED strips come with one; I had plenty of suitable ones lying around).\r\n* A few small scraps of thin-gauge wire (I think I used 20 awg).\r\n* Soldering iron and related supplies.\r\n* Five 100 mm × 100 mm × 3 mm lithophanes (instructions on how to produce these are provided in the Post-Printing section).\r\n* One small zip tie for strain relief of the power cable.\r\n\r\n*Please click/tap **Like/I Made One** to help other people find this model.*\r\n\r\n*I put a lot of effort into these designs. Even a small tip is greatly appreciated!*\r\n\r\nhttps://youtu.be/r6nVYvqCGN8
