Another add-on for my desk, mouse cable is somethings that is always on the way, the solution is a Mouse Bungee. This is by Mouse Bungee was "One day BUILD!" The arm was printed in TPU but my TPU did not dried properly and the print quality was not the best. The bottom part is a container so you can put some weights, i will use sand but for now i filled with screws. For me this is working very well. I'm using with Logitech G502. PS: Be careful when printing TPU on the PEI i did use the glue stick to avoid damage my PEI. Here you have a video showing in action need more weight :P Have fun.
