Over the last 3 weeks or so I have been playing with Sketchup with the intent of learning the basics and getting a design out of my head that has been stuck in there for a while.
There are many people out there who are much better at reviewing things than I but I will say that it has been very frustrating at times with regular freezing (I put this down to running it on an underpowered machine) but overall it has been fun.
The design was for a ducted fan system, along the lines of the Dyson Air Multiplier, using computer fans with most if not all of the main parts being 3D printed.
The Exploded version
I also need to finish the larger head which is designed to fit on the same body.
