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

thingiverse

Could not find any quick and easy to print Lithophane boxes so I have attempted to design this to hold four 90x90x3mm Lithophanes and have easy mounting of the popular and easy to find usb remote controlled rgb light strips used for televisions approx. 900mm long. I print my lithophanes vertically with 3mm border and base and plenty of brim to keep print stuck to bed. I use http://3dp.rocks/lithophane/ to create the lithophanes with settings as uploaded. I sometimes use a little curvature setting from 5 to 15 to help the lithophane stability while printing and you can see om my printed model some have curvature. The main box structure should be able to print with no support, but would only appear on cabling hole. The tube is 0.5mm thick so is designed to print in spiral mode, and I recommend with a brim which can stay attached. Update 25th March 2018 : added tubeV2 which is two permieters thick as it is more rigid for prining in normal mode. The top should be printed up side down. Update 25th March 2018 : added 20mm helper discs which are spaced at just under 90mm so I print lithophane vertically and add tese to the print to give more virtical stability. Assembly is fairly simple. Wrap led strip around tube and use a little wire or similar with holes to keep 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 main structure has inserted into top piece. Connect to suitable usb source which should be 1 amp or more, turn on and enjoy.
