I had wanted a clamp to hold my keyboard on my desk. I found quite a few but the other ones i tried either did not stay on the desk or broke. This model was inspired by another model on this site called off desk keyboard holder, but i found that it's screws were easy to tighten and that it was made too lightweight even when i printed it out of carbon fiber the part that you clamp to the desk would break. Anyways I hacked this together in bambu studio so it's nothing amazing
