CR-10 Solid Bed Mounts Remix

After using the solid bed mounts for a couple weeks checked them out and noticed they were mushrooming from the heat of the heat bed. They were printed out of PETG so nylon or ABS might have worked better but eventually would probably would have the same issue. I looked up spacers on McMaster Carr and came up with some 20mm long x 8mm diameter aluminum spacers for M4 bolts I felt would work better then pure plastic. Since I still needed to make a stain relief bracket I redesigned them to have these spacers press fitted into them.

Extra feature I added to the strain relief is some snap tabs on the cover and holes in the strain relief bracket to help keep the cover on top.

McMaster Carr part number for the aluminum spacers is 94669A062. You will need four of them.

I just printed them out and everything fits as anticipated, will see after couple of weeks if this solved my issue.
