GEETECH I3 PRO C or ANET A8 spring coil cups

Spring Cups. I made them as some others i printed where too loose fit or to thin to be durable.

They fit A8 or GEETECH I3 Heatbed Coils. Freecad Source is included for easy adoption to any spring coils.I assume they can be used for even more than heatbed suspesnion coils.
