Lithophane LED Frame

prusaprinters

<p>I needed a small present for my fathers Birthday and decided to print a Lithophane of him and my mother. <a href="https://tool.itslitho.com/CreateModel">I used this website to design my Lithophane.</a> I decided to design and print a frame with integrated LEDs so the picture is visible even when its dark.</p><p>The good thing about the frame is that you can push out the picture and easily replace it with another one.</p><p>The Litho its designed for is 119mm*78mm*3mm with a frame thickness of 3mm (that part will be hidden behind the frame)</p><p>If you want one in a different size i included the fusion 360 file(sorry for the messy file structure, i'm not a fusion expert).</p><p>I split the back of the frame off, so its easier to print and doesn't need as much support.</p><p>A few things to look after:</p><ul><li>do NOT use the Gcode file, its always a better idea to slice it yourself so that it's safe to print</li></ul><p>&nbsp;</p><ul><li>make sure you use a power adapter with enough ampere and the right volt range that matches the one of your LED strip.<ul><li>i used <a href="https://www.teich-filter.eu/solartechnik/volt-watt-ampere-rechner/berechnen">this calculator</a> to check if my 12v 1 Ampere was enough</li></ul></li></ul><p>&nbsp;</p><ul><li>depending on the LEDs you are using they could get hot and therefore bring the plastic up to or above it's glass transition temperature. It's &nbsp;recommended to test how hot the LEDs get in advance or/and use a material with higher GTT<ul><li>&nbsp;in my case PLA was good enough</li></ul></li></ul><p>&nbsp;</p><ul><li>glue the LED-Strip to the side walls and NOT to the backplate - otherwise you will see light hotspots through the litho and we want an as evenly lit lithophane as possible<ul><li>LEDs with up to 13mm width will fit. the frame without editing the files</li></ul></li></ul><p>&nbsp;</p><p>parts i used:</p><p><a href="https://www.amazon.de/gp/product/B08HQY7J34/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1">Switch</a></p><p><a href="https://de.aliexpress.com/item/32897276867.html?gatewayAdapt=glo2deu&amp;spm=a2g0o.order_list.0.0.21ef5c5f5yKwyG">LED's</a> - its probably cheaper to go with an LED-strip with white/warm white only… i had a few leftovers of that Strip and that's why i used these (all i connected was the WW channel).</p><p><a href="https://de.aliexpress.com/item/32965522025.html?gatewayAdapt=glo2deu&amp;spm=a2g0o.order_list.0.0.21ef5c5f5yKwyG">Power Jack Adapter</a> - the frame is designed to use a Female Adapter as the power adapter already had a male one.</p><p>&nbsp;</p><p>Hope you like the idea and it it useful to you/give you an idea to design your own frame.</p><p>If you have questions or i can help you somehow just write a comment.</p>
