Porter Cable 690LR CNC spindle support gasket

This is a design for a gasket to be used with the spindle supports for a Porter Cable 690LR CNC spindle support I designed for my homebuilt CNC machine. To be printed with a FLEX type of 3D printer filament, this is intended to allow for the use of metal (aluminium) backing plates to secure the assembly.
