Foil Mast Board Protector

Board Protector to save wear on your board. Suggested by some manufacturers.
There is a 3mm thick and a 0.5mm thick version with 140mm Bolt Hole Length spacing. The 3mm has angles (chamfer) and the 0.5 does not. You could always scale the 0.5mm one in the Z axis to make a different thickness.
There is also a 0.5mm with both 140mm and 165mm Bolt hole length spacing.
All versions expect a 90mm track spacing. 140mm spacing in the length dimension is typical for Alum masts and 165mm is typical for Carbon Masts.

I found using the 0.5 will allow you to have more screw threads still engage.
Please DONT USE if you can't have at least 4 full turns of screws engaged with the nut in track, depending on sport you can have incredible torque on those screws, so you need enagement of screw.

Printed 0.26mm layer height, I used 4mm brim to assure bed adhesion.
PET or ABS suggested, but PLA would work.
