ANET A8 Printer bed mounted camera arm for Auto Level

I've got auto bed leveling installed on my printer and wasn't really using the spring mounted bed adjusters anymore, so I hard tailed it with some printed spacers and a camera arm that mounts to the bed in place of one spacer.

I'm a little worried about the bed softening the spacers and arm mount, so I'm going to kill two birds with one stone and put some cork insulation on the bottom of the heated bed and use that to insulate the spacers from the heated bed.

I had tried some other mounts
