Cold frame hinge pin

I constructed five robust frames utilizing the provided files as references. To assemble these frames, I employed PEX 1/2 inch pipe, which is commonly sold in three-meter straight sections. However, I sought to enhance their functionality by incorporating hinges that allow for easy opening and closing. This design modification also serves a practical purpose: it provides protection from wind while enabling me to adjust the frame's position by a few centimeters on warm days to facilitate ventilation.
