Light mount for Ender 3, on Pi Camera Cam holder

thingiverse

This is a light mount that fits the Raspberry Pi cam holder found at https://www.thingiverse.com/thing:2886101. It replaces the back cover of the pi cam. Unfortunately, the author of the cam holder design used a license that does not allow for remixes, so I cannot include the STL of the final back cover including the lights. To reproduce it, you will need to follow these steps: - Download the files for this project. - Download the cam holder files from https://www.thingiverse.com/thing:2886101 and place the file "Housing_back.stl" in the same directory as the SCAD files from this project. - Use OpenSCAD to load "housing.scad," render, and export as "housing.STL." The "housing.scad" file is used to place the pi cam back cover at the right coordinates before allowing a merge with the lights. - Merge the models "box.stl" and "housing.stl." To do this, I used Meshlab because OpenSCAD failed at doing the union of the two models. Import the two STL models in Meshlab, then do the merge using "Filters->Mesh Layer->Flatten Visible Layers." Export as STL. - Print, no change of orientation needed, no support required. Sorry for the complexity. This mount was designed for cheap lights found on Aliexpress at https://www.aliexpress.com/item/24V-LED-Bulb-Car-Auto-Front-Lights-1156-22SMD-P21W-BA15S-Brake-Lights-Lights-Turn-Lights/32890129370.html. There is a space in the back of the light box to fit the wires and connect the two lights together. The vendor of the lights advertised them as 24V, but I saw a comment from a client stating that they were actually 12V lights and that 24V would kill them. I tried 24V, and they were very hot in just a few seconds, with a smell of burn. So, I wired them serially to get 12V for each (see pictures). It's already very bright. Please read the important information about the original cam holder at https://www.thingiverse.com/thing:2886101, which also applies here. The tolerances are very tight, and the front cover may be difficult to slide. SolidPython and SCAD files are included.
