Hi Mark
I don't know if this will be regarded as advertising or whether this is frowned upon in the Forum, but as a new resident of Mellor I thought I would join the forum and say 'hello'.
I have been involved with 3D printing for many years now, initially as a customer of the large 3D printing service bureaux and more recently as a small provider myself. I now own and run four printers, all of which I built myself as a hobby. I was intrigued by the idea of self-replicating, rapid-prototyping machines, otherwise known as the RepRap project, and used each printer to print the parts for the next one. I don't run a commercial 3D printing business, but I do provide a small scale design and printing service in my spare time, which helps to make the hobby self-financing.
I am pleased to say that I have been able to complete the prototyping work that you referred to in the initial post and would be happy to consider other requests from local residents. You can read reviews from other customers at
