Gym equipment Pull-up bar and Dip construction Free 3D model

This is a simple design of a construction used for pull ups, dips and other abdominal exercises. Because I made this for personal use, most of the joints would be made with screws and not by welding. The main reason for this is because I don't thrust my welding completely but if you can weld good enough, you wouldn't need a single screw here. The total weight of the construction would be around 115kg, the profile I have used for this is 50x50 with a 4mm thickness.

Feedback is welcome!
