This will not work for the Ender 3 Pro. If you have an Ender 3 Pro, you will need to use this adaptation by Pixl3D:
This handle lets you to move the build platform along the Y axis without burning yourself. I designed this to be mostly hidden under the bed, providing a clean look, and the handle doesn't get in the way of the USB and MicroSD ports, leveling adjusters, etc.
To install, just remove the front two leveling adjuster wheels, attach the handle on to the bed screws under the bed, reinstall the leveling adjusters over the handle, and re-level the bed.
I removed the file for the GoPro camera mount version, due to problems reported by other users. I did it by request to try and be helpful, but I never printed it to test it out (I don't have a GoPro). The CAD software I used to combine the handle with the camera mount has some issues with generating STL files and I won't be using it in the future.
Doesn't Matter (I used .2mm)
Brim recommended. supports necessary. ABS recommended. If you use PLA, please comment to let me know how it holds up to the platform heat after a couple of weeks.
