Cool! This was interesting to see.
On the design: It looks like it could be good for laser cutting but I doubt it will do more than CNC engraving wood. Would love to be proven wrong. I think the screws are too close and the leverages too large to be solid enough for cutting. We cpuld simulate it to verify the weak spots. No problem for plotting and laser cutting though. I was surprised by the deflection of the Indymill which has more metal parts.
On the CAD file: I could easily find my way in the file. I generally constrain more (also importing shapes from other Bodies) which makes it more automatic but also more error prone and harder to calculate. It will be interesting to see an assembly of these parts too.
Looking forward to updates from this build.
We have a few Tuxedo computers and some other Linux brands at our company and are generally happy about them. Cheaper devices have a less than perfect keyboard (though I liked the one on the slimbook) a worse camera and microphone (though some are very ok).
I'm very happy with these Linux devices. The few makes for which we needed parts also supplied them but sending the device their way for repair took longer than we'd have wanted.
