Ive created this OV5640 camera holder for cheap AliExpress cameras to observe my prints remotely with Octoprint. Ive used the existing Creality Nebula holder for mounting the piece and added the HappyCam holder to hold the OV5640 PCB with the camera.

Changes to the original versions:
Ive printed with a 0.2mm Noozle at 240C and 60C bed temperature with generic black PLA. Layer height of 0.12 and speed of 100. I was able to achieve pretty good results with those settings.
The author remixed this model.
Ive mixed both 3D models together. I wanted to create a camera holder for cheap AliExpress cameras for my Ender3 v3 SE but could not find matching holders.
