ENDER 3 endstop mechanical switch mount (for timelapses)

thingiverse

I really wanted to add timelapse capabilities to my ender 3, but i did not want to have the overhead/implications of running octoprint on a Pi. My solution is inspired by Devin from Make Anything: https://www.youtube.com/watch?v=Is10iN43UjI Essentially, he hacks his gcode in his slicer software, so that after each layer, the Bed moves all the way to the front, and the toolhead moves at the max X position on the gantry. It then hits a limit switch, triggering his DSLR camera. He then can make the timelapse, and stitch everything together in his editing software With that idea in mind, i designed a small piece that clamps (using V nuts just like the ones most printers use) to the gantry, and holds a mechanical keyboard switch. in my case, when the toolhead moves to the maximum allowed position on the X gantry, the direct drive mount for the extruder motor actuates the switch. You might need to mess arround my design to adapt it to your toolhead setup, but you can find the Fusion 360 file in the thing files tab. I will upload the rest of the project in a few days: the switch will be wired to an ESP32 that will take pictures everytime it gets actuated. Keep in mind this thing is not exclusive to timelapses: you can use it as an endstop switch, or warn you audibly when your printer moves to a position you deem dangerous, etc. Have fun with it!
