Fume Extractor
I need a fume extractor for soldering, not too bothered about filters as I do this in a ventilated area just dislike when the fumes go directly into my eyes

Dual directional control
I have now printed the parts but I'll get to that later because I was spinning the fan part and realised that the switches I was using ave 3 modes, 2 on and 1 off. Due to this I was thinking about how I could make the motor spin both ways- better if it is purely hardwired.
Now on another project I was doing some research into H-bridges and realised this is exactly what is needed for this project and so I set out designing a manual and purely hardwired H-bridge with my switches and think I came up with a pretty good design that I was able to simplify down well.
It requires two switches but these will be mechanically attached together to prevent shorting out during use.
These will work together with a potentiometer to determine the direction and the speed of the motor.

Finishes modelling
Created the base area for all the electronics and some holes for the switch and potentiometer to fit through. This means that the whole model should be done and is now ready for printing and I have actually spent extra thought processing power on this project making it print without supports.

Continue modelling
After this I modelled the housing for the DC motor that I will use and added the 6mm holes for the 6mm dowels that will form the main hardware that holds these products together.
and then learned to use and used the loft function (my new favourite function) to create the outer form of the casing between 3 sketches on different planes.

Start modelling
I started by looking for some kind of documentation for modelling a fan but was unable to and so I looked online for some images. Due to the fact that the fan will displace different volumes of air based on the pitch of the wings I will be modelling two different fans and using the best, established after some testing.
To model the blades I started with the lower profile and then offset the bottom plane to create the top profile before lofting between these two profiles.
Before creating the center section and using a circular pattern to finish the blades.
