Titan Multi Garden tool hand nut

I bought this Titan 4 in 1 garden trimmer around 10 years ago and it has stood up well to the use and abuse, trying to keep my garden in check. Somehow along the way, one of the hand nuts has got itself broken and it doesn't seem like you can buy any spares for it, so I set about 3D designing and printing one.
I took the vital statistics from an existing hand nut and produced this. Hope someone finds it useful, as it will fit any machine that uses M6 clamp bolts, I would think.
