The file 'Greenhouse Frame Track Clip 3D Printer Model' is (stl) file type, size is 189.4KB.
Most standard aluminium frame greenhouses have frames with an internal facing track. These clips fit into the tracks on my greenhouse (perhaps yours too?) and rotate 90 degrees clockwise to lock in. They are designed to allow string to be attached. They are trivial in design terms, but useful for supporting plants etc.
