I’m all a-tingle! Today is the day when the designs for 622 start to get realized.
I just uploaded the first files for 3D printing at Shapeways. I’ve broken the printing in orders parts – the first for the engineering parts required to make a working model, and the second will be for the details. This not only deferred $130 of spending, but may also enable me to take advantage of new technologies when I finally get around to printing! After all, the last engine took four years to complete, and that’s a lifetime in the technology business.
PPD is a more hands-on arrangement, and I emailed the artwork. I won’t find out until at least Monday if my artwork is even acceptable. For the next time I’m producing artwork for etching, I must remember a couple of things.
- InkScape has a command on the edit menu to enable you to select all items with the same fill colour; I laboriously selected each individual tab and fold line on three of four sides before finding it.
- I should have designed the parts to allow for etching in OnShape, rather than leaving such considerations as minimum widths to the layout stage.
- InkScape introduces some artifacts in the final pdf render. I spent a couple of hours today reviewing each pdf for faint lines where one shape meets another shape.
