310D D300vs FSR and Bed Clamp (with alignment tool)

Edit 05/02/2019: Added an alignment tool to prevent binding.

I upgraded my d300vs/+ to a flex system with a 310 diameter.

This mount is to be used instead of the original bed clamp and fsr mount, as it's all integrated. The idea is that the mounts will self align to the mag base. I am using the mag base with the original aluminum heat spreader so the stack is:

PEI Sheet on SS Flex sheet
Magnetic Base
Aluminum Heat Spreader
