Curved Lithophane Box - Micro-USB version

thingiverse

This is a remix of [DCRobotics' Curved Lithophane Box](https://www.thingiverse.com/thing:4698911), which I like very much. ### **Changes** I made: * Added a "lip" at the front of the lid to match the design of the main box/body and cover a potential gap between the lithophane and the lid * Increased the main box/body's internal height to 75.5mm to better fit a 4:3 picture (75mm height according to 100mm width) and still have 0.5mm tolerance * Micro-USB powered * variants without/with(v8/v9) switch KCD11 (smaller than in original design) * Minor design changes to increase print-ability In the original design's comment someone already asked for the "lid with lip". The lid of my design still fits the original box/body of the original design. To make the USB port integration easier the design is based on a small microUSB breakout board. These are widely available on various marketplaces. The USB-Port/PCB can either be glued in or screwed in with two M3x6 screws. As USB provides 5V I used 5V LED stipes to not have to change/adopt the voltage. Ideally it has the LEDs mounted relatively close to eachother what allows 4 LEDs per side (see picture) and offers a real good brightness. USB "GND" connects to LED "-" USB "VBUS" connects to LED "+" **Please review the good documentation of the [original design](https://www.thingiverse.com/thing:4698911) about how to print the lithophane, box and lid!** Just like DCRobotics I added Fusion 360 project file (*.f3z) for anyone who might want to edit/remix it. ### BOM (= Bill of Materials = things needed): * microUSB breakout board (e.g. https://s.click.aliexpress.com/e/_DcZ5YxD) * 5V LED strip (e.g. https://s.click.aliexpress.com/e/_DFdhvuT) * optional (v9): KCD11 switch (15x10mm, e.g. https://s.click.aliexpress.com/e/_DDDGyVp) ### Change-Log: **2022-12-18 (v7):** Initial upload of all files as version v7 **2022-12-20 (v8):** Changed internal height of the box to 75.5mm to fit well with a 4:3 picture with 100mm width and 75mm height (and still have 0.5mm tolerance). Lid is unchanged. **2023-01-03 (v9):** Added Version v9 with cut-out for a switch (15x10mm "KCD11" which is smaller than in original design) **2023-01-07 (v9.1):** Minimal optimization of the switch cut-out to better fit. Replaces v9.
