Lithophane light box

Description

This is a lithophane light box that I designed for a specific sized and curved lithophane (links and info later in the description). It is definitely over engineered and not for everyone, but some people liked it and wanted me to offer it on Thingiverse, so here it is. NOTE - I would recommend using eSUN PLA+ Cool White for your lithophane as it gives very good contrast and definition. That is what I used for the lithophane images I have posted here. My box takes 12V Super White COB led lights and requires a cord. (I may design a battery operated one later) - I have several different configurations of LED light mount panels that will work. They are made for either the 18-SMD or 24-SMD lights. After testing, I recommend using the 24-SMD lights (slightly larger) as they give off slightly more light and (believe it or not) they use slightly less amperage (so less heat). My version also uses a power distribution block but that is not a must. You could wire the lights directly to the switch and the power input module I suppose (and do away with the distribution block) but you would still need the small interior printed piece with 4 screws to hold and cover the power input module. These are the 24-SMD lights. BE SURE you order the WHITE lights and NOT the ICE BLUE ones (unless that is the look you want). https://www.amazon.com/gp/product/B00J23EA7U/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 These are the 18-SMD lights. https://www.amazon.com/gp/product/B00J23EA2U/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1 This is the power distribution block that I used. https://www.amazon.com/gp/product/B09D3BV22M/ref=ppx_yo_dt_b_asin_title_o06_s01?ie=UTF8&psc=1 Here are the power jack socket that I used. (These are the specific size that fit my design). Other sockets seem similar but are NOT the same size so I highly recommend using this link. https://www.amazon.com/gp/product/B079R9WCG2/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 Here is the power cord that I used. https://www.amazon.com/gp/product/B00Q2E5IXW/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 You will need some extra wires to make all of the connections. I used these connectors so I don't have any soldering on my wires but you can connect the wires whatever way you are comfortable doing. https://www.amazon.com/gp/product/B0774NMT1S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 These are the power toggle switches that fit my design. https://www.amazon.com/gp/product/B011U1NU90/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 These are the spade crimp connectors that I used (pink for 18AWG wires). https://www.amazon.com/TICONN-Disconnect-Connectors-Electrical-Assortment/dp/B08BZ972B5/ref=sr_1_1_sspa?crid=14INOA464GT3N&keywords=crimp+spade+connectors&qid=1648852922&sprefix=%2Caps%2C73&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzMkFEMTM5RDA4R1lSJmVuY3J5cHRlZElkPUEwNjE0NDEyWUtBMjZOMUtJQzg1JmVuY3J5cHRlZEFkSWQ9QTA2MDM4NDdDODRTNVZKRU1LS04md2lkZ2V0TmFtZT1zcF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl You will need FOUR M3 screws (10mm-20mm) to hold the power distribution block (or just the cover plate) in place. NOTE: I printed the LED light panels AND the light diffuser panel in PETG just to help with the heat generated by the LEDs, although they just get a little warm, not that hot. I recommend that you start with the LED light panel that holds TWO 24-SMD lights. That should be enough light for most lithos and then go to the 3 or 4 (24-SMD) panels if needed. I recommend the 24-SMD panels over the 18-SMD panels just because you get more light, less heat, and less power used as well - believe it or not. Also, I put small holes behind each light to allow for a little better heat disbursement from the lights. PLEASE NOTE: This is designed to hold a specific sized lithophane print. I used this website to generate the STLs for my CURVED litho prints. https://lithophanemaker.com/ The litho is almost square so the main image that you should use should be close to square. The size of the image that I used was 5.42" wide and 5.38" height. (or 13.76cm wide and 13.65cm height) YOUR IMAGE SHOULD BE AS CLOSE TO THAT SIZE AS POSSIBLE. - Look in my images for an image of ALL of the litho settings that I used to produce my litho STLs that fit this box. ALSO - The TOP piece is just a press fit. You just need to press the front and back sides of the box in slightly and you should be able to just press the top down to fit in place. It could be a snug fit, depending on how well you have your printer's printing dimensions set up.
