I ran out of inventory. I have been doing a lot of 3D design and prototyping. I am hoping to get a job doing mechanical engineering somewhere. Rapid prototyping would be ideal. I still have a box of unfinished knobs and I have a lot of collars left. There are around 63 knobs so I was going to mass email previous customers and see who wanted one. They are not done yet though and I have a project I am working on at the moment for a patent holder. I’ll keep you informed when things change. Thanks for the kind words. I am OK. Talk to you later. Take care
