Ender 3 GoPro bed mount for magnetic spring steel bed

thingiverse

I wanted to make the original much more robust, but also I wanted it to work with my magnetic PEI-covered spring steel bed. I moved the GoPro mount further out and included some slots to use two glass bed clips (see pictures) to secure it. Print as shown with supports. Cleans up fine once you've removed all this. Take care removing supports in the GoPro mount area as these can snap relatively easily. I would suggest making this out of PETG as I'm not sure how well PLA will stand up to the heat from the bed.
