Description:A De Laval nozzle for supersonic kinetic spraying.
Wants:Nozzle dimensions (mm):
- Inner diameter: 10
- Throat diameter: 6
- Exit diameter: 8.8
- Length of the converging section: 40
- Length of the diverging section: 100
The above dimensions must be exact. However the size and shape of the nozzle externally is left up to you, considering the following:
350°C air enters the nozzle at 6 bar. It is connected to the air compressors 1/2" male adapter. Therefore a 1/2" female thread will be needed to connect the parts together.
Suspension liquid enters the gas flow in the supersonic part of the nozzle and is atomized by the gas cross-flow. The tube connected to nozzle which supplies the suspension has a 1/4" male adapter, so a 1/4" female thread will be needed.
The design does not need to include the female threads as they will be added after the CNC process (another version of the design showing these [threads] would be favorable). Just know that the space and position of these threads will need to be factored into your design.
Thank you very much.
P.S. The software used for the CNC process is unknown at the moment, so if at all possible, please include a few of the most popular file types.

The gentlemans shaver
We need a design for a shaver handle. The design should have an exclusive look to it, not "spacey" as many established brands are. Keywords for the design could be "gentleman, scandinavian, hipster, modern man, elegant, James Bond, simple" and such. What we need is a design made in CAD, and ultimately files ready for production, our current setup requires .dwg or .dwt files. But we would like to see an realistic 3d render of the handle. There are though some specifications for the connection between the handle and the razor blades that should be met. Since the connection is an standard set of from our razor-blade production partner. In the attached files there are an example of an handle and the lock mechanism, so the way the blades are connected and the sliding lock works should be thought into the design. It's for the scandinavian market, so the design should fit in there, and should ofcourse have a good grib, size and weight to it. We have a target weight of minimum 50-60gr to the handle.

Brick of Money
The goal of this project is to design a desk ornament that is a conversation piece. https://goo.gl/wc3ueb There are 3 aspects to this product: 1: The foundation: A rectangle of solid metal. Should have an expensive high end look. A bar of silver is the only thing I can think of as an example foundation. https://goo.gl/wMySnL However, I am going for more of a brushed nickel look. 2: The casing that sits on top of the medal foundation. This casing is either made of glass or plastic and will be glued to the medal foundation. 3. $500 in one dollar bills will be inside the glass casing. The attached image is not high end looking but should give you a basic idea of the kind of product we are looking to develop.
