A team effort, having seen something similar in Engineering in Miniature I made a rough sketch, which my nephew drew up and a friend 3D printed. They are holders which screw to the wall to hold ARC C3 quick change tool holders. There are more photos in my album. They work well, the countersink was not right for the screws I have (my fault for not measuring and specifying correctly) so I made them bigger. I have a mix of Arc and Chester tool holders and had not realised that the knurled locking nut on the Chester ones is bigger than the Arc ones so that stops those from fitting on the holder. I have a couple of spare Arc ones so swopped the nuts over and will make new smaller nuts for future use. The files will be uploaded to Thingyverse soon, I will let you know if anyone is interested.
