I have a bit of a collection of mechanical keyboards, each with a different type of switch. I got tired of having some in my closet and others taking up desk space so I came up with this solution. These brackets are designed to be adhered to the wall with some strong double sided tape so there are no screws to be seen when a keyboard is off its shelf.

The small size I designed for ten-key-less (TKL) keyboards, has an arm length of 160mm. The medium size I designed for average full size keyboards, the arm length is 175mm. I may eventually draw a larger size if necessary but I think if they're any longer it will become too unstable without modifying the back of the bracket.

Version 1.0 has filleted edges which look nice in the model but unfortunately didn't print very well on my printer. Version 1.1 removes the fillets and also reduces the thickness of the part as I determined it wasn't necessary to be so thick.

I uploaded the SolidWorks part files for each version as well so anyone can make further modifications.
