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.

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.
Design a toy stroller. I have an example. Just the frame not the basket. I doesn't need to fold up. I would like the tubing thicker then the one in the picture.
Cat Earred Headphones
We want a set of headphones designed that have cute cat ears designed on the top of the headphones. The mockup that we will include uses Beats Solo HD headphones as the template. This an easy way for us to portray the aim of the project, as we want the final outcome to look sleek and simple, but not exactly like Beats. We want a redesigned set of headphones that has fashionable cat ears on top suitable for young 20 year old females. Make 2D mock ups to give us an idea of what you have designed, then also to make up plans that can be sent to manufactures for immediate production, preferably in a cad format that can be used to 3D print the shell. Color, style, aesthetics are all up to designer, but general preferred color themes will be for white to pair with pink, and baby blue to pair with very light red.
Intricate Wings Design
