Top-Swappable Crystal Lamp

I was inspired by other crystal lamps ( namely the [Crystal LED Lamp](https://www.thingiverse.com/thing:3391442) ) but wanted something that could be customized more. The base is specifically sized to fit two variants of a PCB I developed, either [WS2812 5050](https://github.com/duh102/kicad-ws2812-city-light) LEDs or [discrete diodes with ucontroller PWM](https://github.com/duh102/kicad-rgbw-mosfet-panel) Programs for each: [WS2812 variant](https://github.com/duh102/glowcity-ws2812) [Discrete diode variant](https://github.com/duh102/rgbw-circle-panel) There's a ton of toppers I developed, most of which need some support to print properly. There's 4 main styles: * Those that themselves cover the whole PCB ("circular" files) * Those that are based on a hexagonal tesselation ("hexagon" files) * Those that are based on an intersection of two squares base ("square" files) * Those that are based on an octagonal base ("octagon" files) The circular ones can be printed entirely in clear PLA and will work as-is. The others all have "base" pieces that act as a mask to ensure there's no light leakage outside of the topper, and slot in nicely between the base and topper. There are three variants of the base: standard, deeper, and with controls. The standard is the variant I recommend using if you put together copies of the PCB, as it is low profile and lets the topper be most of the visual impact. The deeper variant I created to make iteratively programming the MCU easier, as it has enough room for a surface mount 2x3 ISP header while also sitting completely into the base. The controls variant has room for a controls PCB. I don't recommend printing it, as I never got the controls working nicely. I don't have much experience with reading analog voltages and I had a lot of trouble removing noise from the circuit. Coincidentally, the potentiometer cap file is intended to be used to top Bourns PTV09A-1 potentiometers, which I used in the control PCB. I've also included the wings 3d files I used to create the various toppers. I recommend the following steps to create new toppers/bases: 1. Use one of the existing toppers or one of the bases to create a fitting template shape, and build up your new topper 2. Extrude the base of your topper about 10mm, then export it as a solid shape 3. Download [Meshmixer](https://www.meshmixer.com/), install it, and import your solid shape 4. Hollow your part (I use the default wall thickness of 2mm) 5. Use a plane cut to cut off the extra 10mm you inserted, leaving behind a nicely hollowed part Most of the time this will require supports, but you may be able to design sneakily self-supporting parts.
