simple bracket to hold a keyboard on top of a 4040 aluminium profile rail. Most of the holders I've seen mount to the sides but I wanted to keep the width compact so this works for me - see picture I have it tucked on the side by my seat and I can grab it easily.
designed for use with M8 bolts and t-nuts with space for a washer up to 16mm wide. You can likely use M6 bolts/t-nuts with a washer too but haven't tested this.
hopefully you'll find it useful.
