GoPro Mount - MK3S specific remix

This is a remix of the heatbed camera mount for sport style (GoPro) cameras. This remix makes the parts fit specifically for the MK3S heatbed that uses at 5.5mm spacer. I reduced the height of the Slide Mount specifically to fit this bed. The other files were not changed. Based on thinning up the Slide Mount, I printed it at 40% infill, but all the other parts at 20%.

I found that the Slide Mount needed to be backed out from it's fully engaged position (with the heatbed) by a couple mm in or
