About this 3D model

Parametric U shaped clip for clipping sheeting to PVC piping for building custom cold frames and greenhouses. Using Schedule 40 White PVC pipe is a common way to build your own designs for green houses, cold frames etc. For example: http://doorgarden.com/10/50-dollar-hoop-house-green-house This U Clip is used to attach clear sheeting or netting to the frame. The stl's are for 3/4 inch PVC (approx 1 inch outside diameter), but the design is parametric, so you can change it for any diameter of piping. Printed at 100%, the result is strong. I've put it through 60 clip/unclip cycles over single and double sheeting, and had no breakage or looseness.
