Rostock Mini Round Print Base (Trinity Labs 160mm round kapton heater)

I purchased a 160mm round kapton heater from Trinity Labs (with a matching 170mm Borosilicate Print Surface) and needed a mounting solution for my Rostock Mini.

This is a print base that uses three M3 screws with knobs (under the rostock-mini base) to make it easy to adjust. It is spring loaded so it can survive minor miscalibration mistakes.
