The package from PPD arrived today and like a ten-year-old freeing a puppy on his birthday, I couldn’t wait to rip open the package! And then cut, and then rip some more, for PPD don’t mess around when it comes to getting their product to you safely. The two sheets were wrapped in tissue, then […]

I think if I’d been more cunning, I almost could have fit two whole models on there. As it is, there will be plenty of leftover etch and there are doubles of all the riskiest parts. […]

Using OnShape to create etching patterns in InkScape

I’ve been experimenting with OnShape sheet metal models to produce patterns for etching parts. Being designed for ordinary bending processes, OnShape is not directly applicable, but I think it is close enough for my purposes. Here are the sheet metal model parameters that I have found work in OnShape to produce drawings that match the […]

OnShape and etched fold lines
