Lithophane Light Box

thingiverse

This is my take on the Lithophane lamp/Gift box, which has been designed to accommodate flat 100 x 100mm Lithophane panels all around a solid top panel. I created 3mm thick Lithophanes using http://3dp.rocks/lithophane/, adding a 3mm border under settings in Image settings. A 220vac 4w LED Bulb is used as the light source, paired with a bulb fitting that screws into the bottom. The bulb fitting can be chosen based on the correct voltage, and it's available at https://www.banggood.com/Non-Dimmable-E27-4W-10-SMD-5730-LED-Pure-White-Warm-White-Light-Lamp-Bulb-AC85-265V-p-1138354.html?rmmds=search&stayold=1&ID=3837&cur_warehouse=CN. Mounting holes are 5mm deep, and the length of M3 self-tapper needed can be calculated by adding the thickness of your lamp holder. The mounting holes are similar to those found in https://hydroponic.co.za/hydroponics/e27-lamp-holder/?gclid=Cj0KCQjwxN_XBRCFARIsAIufy1YptC5M1RjLr7rU-P5_vHvyS06yx8kTufbkQo3G-_3V8JLmCSaEfNIaAviPEALw_wcB. The base includes a cable lock to prevent the cable from pulling out. Two M3 x 16mm are used to secure the cable lock, and the cable is 6mm OD. A 2 pole switch with a cutout dimension of 13 x 19mm is used, available at https://www.banggood.com/1Pcs-2Pin-Snap-in-On-Off-Rocker-Switch-Control-Black-p-920431.html?rmmds=search&cur_warehouse=CN. The box is held together with 8 M3 x 20 self-tapping screws.
