About this 3D model
Simple part, easy to print and very strong. Its design transfers as much of the weight into tension and compression of the frame rather than putting a large torque near the screw like others I have seen. Because of this it only requires one screw into a wall stud. The two snowboards pictured have been hanging for over a year and yet I sleep soundly underneath them. I would not exactly recommended PLA as it gets brittle in a humid environment. PETG, ABS, or better would be preferable. STP file included in the zip which can be easily edited by almost any cad software.
