Measures are taken from <strong>inside the arc</strong></p><figure class="image"><img src="https://media.printables.com/media/prints/211757/rich_content/75461738-1926-4d12-b6f2-2af74273eb14/captura-de-ecra-2022-05-23-013601.png#%7B%22uuid%22%3A%2299e7e332-ea7f-493c-8c25-b8d7966679e4%22%2C%22w%22%3A955%2C%22h%22%3A413%7D"></figure><p>The remaining measurements are simply the <strong>Thickness </strong>and <strong>Height </strong>of the litho, and it should generate the correct stand and optional lid.</p><p>You can further customize the <strong>wires </strong>and <strong>switch</strong> hole parameters, and the<strong> lid screws</strong> to your taste to fit the material you'll use, or set them to zero if you don't want them.&nbsp;</p><figure class="image"><img src="https://media.printables.com/media/prints/211757/rich_content/2b99bc87-380e-4563-a09b-1153b352f927/captura-de-ecra-2022-05-23-021012.png#%7B%22uuid%22%3A%22aab4df46-9a6e-4f90-9bd9-ddb11f9c50fa%22%2C%22w%22%3A1105%2C%22h%22%3A501%7D"></figure><p>Be aware the this Frame “grabs” some 3 to 5mm around the lithophane, so If you are creating a new lithophane just add a border, or if you don't want to mess with the lithophane editor, just edit the picture with a black bar around the outside of the image</p><figure class="image"><img src="https://media.printables.com/media/prints/211757/rich_content/b65c1555-b208-440f-b33c-507f94f3ef9a/captura-de-ecra-2022-05-23-021717.png#%7B%22uuid%22%3A%229866a034-cc98-441d-b4d1-2591b1a1a571%22%2C%22w%22%3A1592%2C%22h%22%3A567%7D"></figure><p><strong>To finalize, you'll need some soldering skills.&nbsp;</strong></p><p>How you do the lighting is up to you, but normally I set 4 cut-to-lenght strips of <a href="https://www.amazon.de/-/en/gp/product/B0798SNC6P">5V LEDs</a>. I set them vertically, 2 just beside each side of the switch, the other 2 are set ⅓ of the center side, placed to the center. Avoid putting strips too far out to the edges, as the closeness to the lithophane can cause the single LEDs to stand out. While losing light in the center.</p><p>I buy <a href="https://www.amazon.de/-/en/gp/product/B07NSMN2W7">male-male (USB-A to USB-A) wire</a>, that way I have 2 USB plugs I can use. There are 2 holes for wires in the model, as you can put the wire where it's most convenient for the end use.</p><p>I connect the Strips in parallel and then connect the + to the <a href="https://www.amazon.de/-/en/mmtrade-Rocker-Switches-Lockable-Self-Locking/dp/B07P769WDV">on/off switch</a>, and then to the wire. The negatives are all sent to the wire directly.</p><figure class="image image_resized" style="width:50%;"><img src="https://media.printables.com/media/prints/211757/rich_content/f35dcd9f-1b99-4906-8202-3071ef84c9fc/sem-titulo.png#%7B%22uuid%22%3A%22c810dfc0-d439-4210-aad0-f35b6e73116c%22%2C%22w%22%3A676%2C%22h%22%3A867%7D"></figure><p>Try to keep the <strong>wiring harness</strong> as <strong>close as possible to the center and back</strong> of the piece, since any wires too close to the Lithophane can cause it to show shadows in the lithophane or even light leak from colored wires.
