I was in need of some stabilisers for the desk I built that my printer sits on so I created these supports. They have been working great and the shake from printing no longer causes my table to bang into the wall. The Ends are 48mm to snap securely onto a 50mm table leg and the other end can be screwed directly into the tabletop. Make sure to print with supports on as the one end is much higher than the other, don't print it with the center section at an angle as the resulting steps in the center section are quite ugly and could affect the strength. This was printed in Bambu Basic Black and was my first design, I hope it can be of use to you, but let me know if you have any suggestions.

I have included the STL file if you wanted to adapt this to any other diameter or shape of table leg, the part is in 3 sections in the STL so that you can change either end or the length required. Just make sure to add the fillets on the ends once you have rejoined the part to ensure it is as stable as possible.
