Purchasing this will give you the STL Files to print your own models to use along with the complete plan and parts list for duplicating this camera holder for a Logitech C720 webcam that mounts to your Creality Ender 3. 

This is for use with an Octoprint setup using a Raspberry Pi.  

Using this setup you can make some awesome timelapse videos to share and document your projects.
