This one device replaces an entire gym worth of equipment. You can basically train all the muscle groups and get a full calisthenics workout done at home. Calisthenics is a form of strength training using one's own body weight.
This device is small enough to be carried by a single person and can be used indoors and outside, depending on the weather. It can be welded from steel or stainless steel tubes. Most of the tubes are 5 cm in diameter. The handles are 3.5 cm. The footer-frame is made of 6 x 4 cm profiles. Alternatively, for maximum cost efficiency and lowest weight, it would work fine if all the tubes were 3.5 cm in diameter and the footer-frame was 4 x 2 cm. In that case, it would be good if the footer frame was a bit wider for better stability. All the tube walls are 2 mm thick.
I've made multiple units over the years. This design featured below is the best I could come up with and pretty much achieves everything I need. Feel free to copy. I can take measurements if anyone needs them. Any local welder could easily put this together for you. The approximate cost of the plain steel material for one such unit would be between 80 - 150 EUR, depending on the local prices.
The stainless steel unit below, was made to be sold. It can be dissassembled for easier shipping. Because of the cost of stainless steel it ended up being too expensive. Each unit would have to be sold for at least 650 EUR to be worth the trouble of manufacturing. Because of the weight the shipping cost would easily add a few hundred EUR to the total. I never sold any:)
Adding Gymnastics Rings in your upper horizontal bar will increase the benefits of your workout, since there are unique compound movements only achieved employing circular wooden rings like:

Perhaps you could look to Lego and Ikea for inspiration.
If every bar could be put in place in pre-existing holes or hooks or even clips, the contraption would suddenly be much more versatile, adjustable and portable.
Say, for instance, a shorter person wants to make use of the pull-up bar, it can be lowered, or if you'd like to do inverted rows the bar could be put in the best position for that.
If you could find a way to do that while still keeping the structure solid, the possibilities of what you'd be able to do with a couple of bars suddenly become endless.
I'm imagining something similar to an old-school toilet tissue dispenser, with a compressible pin that allows it to fit in the structure, but expands into place when it is in the desired position.
