Light box for Lithophanes, easy print, designed for USB RGB LED strip

thingiverse

I searched everywhere for quick and easy-to-print Lithophane boxes but couldn't find any. So I came up with my own design that can hold four 90x90x3mm Lithophanes and make it easy to mount popular usb remote-controlled rgb light strips, approximately 900mm long, which are widely available. I print my lithophanes vertically with a 3mm border and base and plenty of brim to keep the print stuck to the bed. I use http://3dp.rocks/lithophane/ to create the lithophanes with settings as uploaded. Sometimes, I add a little curvature setting from 5 to 15 to help stabilize the lithophane while printing, and you can see it in some of my printed models that have curvature. The main box structure should be able to print without support, but only appears on cabling hole. The tube is 0.5mm thick and is designed to print in spiral mode, so I recommend printing with a brim that stays attached. Update: March 25th, 2018 - added tubeV2 which is two perimeters thick for more rigidity when printing in normal mode. The top should be printed upside down. Update: March 25th, 2018 - added 20mm helper discs which are spaced at just under 90mm to give more vertical stability while printing lithophane vertically and adding these to the print. Assembly is relatively simple. Wrap led strip around tube and use a little wire or similar with holes to keep it in place. Feed usb cable through hole. Put cross-shaped piece into main structure into lugs. Slip tube over circular section of cross-shaped piece. Insert Lithophanes into slots in main structure. Put top piece over everything, ensuring each corner of the main structure has inserted into the top piece. Connect to a suitable usb source that should be 1 amp or more, turn it on and enjoy.
