I designed this mount because I became frustrated in my search for a C270 bed mount for my Ender 3 that would work inside of a lack table enclosure.
I initially tried using version that mount directly to the lack enclosure but the video was horrible because the pictures weren't taken at a specific bed location. So the bed was at a different location every frame and made the timelapse impossible to watch. So I tried some that mounted to the extruder arm like the one I remixed from but that had the same issue with the bed moving all over during the timelapse. So finally I decided bed mounted was the way to go as I had no interest in using the octolapse plugin for octoprint. This this creation was born.
While this one isn't perfect, it does a decent job of showing the print bed without hitting against the enclosure's glass or focusing on only a small piece of the bed.
To install, remove the bed height adjustment wheels from all four corners of your print bed, Be careful to not lost your springs. Slide the camera mount on one corner of your bed and align the holes on the mount with the hole used by the bed screw. The mount is made to fit around the spring so don't remove the spring. Run the bed screw back through the holes so that they pass through the camera mount and print base plate. Screw the adjustment wheels back down far enough so your printer nozzle won't destroy your print bed like it did mine.
Please let me know if you have an suggestions for improvement!
Edit: I had to modify my CURA settings to prevent the bed from shifting all of the way forward as it would barely bump the camera and make the timelapse post roll blurry. I just made the bed shift 20 mm less from the forward position
Supports where the mount attaches to the bed can be difficult to remove. I put a flathead screwdriver in the cracks between the mount and support and twisted at different points to separate the support from the mount.
