Virtual dry fit for 622

In typical Panglossian fashion today, I uploaded the STL file for 622’s plastic parts to Shapeways.  I might have hit the big “Print” button, if the bounding box hadn’t precluded the use of their highest resolution machine. It’s a good thing I didn’t because the pause gave me an opportunity to assemble all the parts in OnShape. There I found that the gearbox was going … Continue reading Virtual dry fit for 622

All the parts that are fit to print

I’m just about ready to upload all the printed parts to Shapeways.  To support some of the more delicate parts for printing, and more importantly for shipping, I added some sprues.  I actually started out making a sprue for all the parts, but then I re-read the pricing guidelines for Shapeways and concluded that this was unnecessary. Sadly, my computer decided it wasn’t going to … Continue reading All the parts that are fit to print

OnShape and etched fold lines

Due to flooding, progress on real modelling has halted, and I’ve had to move into the virtual realm.  This is okay, as there is loads of drawing work yet to do on 622. I speculated a couple of months ago that some careful manipulation of OnShape’s new Sheet Metal Model feature might yield a good pattern for etching.  Tonight, armed with an excellent resource on design … Continue reading OnShape and etched fold lines
