Description:
This is constest for a telescoping mechanism with the following parameters. It needs to lift about 3 lbs straight up across a range of from 2ft -5ft with a travel speed of 6"/second both up and down.
There will be bundle of wire running up the inside of the tubes probably about the size of a usb cable and some 3-4 servo extension cables.
All custom parts should be designed to be fabricated on either a makerbot, laser cut out of 1/8" thick material, or exsisting off the shelf components.
The tubes of the telescoping mechanism should be from these square polycarbonate tubes (1/2", 3/4", 1"). www.mcmaster.com/
The bottom of this device and the motor that drives it will mount to a plate of 0.20" aluminum.
Please find a motor which is available for order in the USA.
The motor should be either a 24vdc or 5vdc servo.
Wants:
The primary criteria will come from if the design meets the parameters from the description. Secondary will be the ease of assembly and fabrication. Lastly the elegance and sleekness of the design will be weighed in.
Don't Wants:
We are looking for an elegant clever design. We do not want huge mechanisms or kludge.
Software:
- SolidWorks

Can you extend the time of the contest?
I will accept AutoCad/inventor. In the final set of file please save all solid models as the native autocad format as well as .stl and/or .iges
Is Solidworks the only program you can work with? No AutoCad/Inventor?

Liquid Filling, Measuring, Cutting and sealing Machine
I need a Liquid Filling, Measuring, Cutting and sealing Machine designed, the machine will be filling liquids such as fruit juices onto plastic bag and sealing and cutting the bags into tubes of different measurements, the machine should be fully automatic, the use should only specify the size of the tube required, the number of tubes to be filled and the machine should be able to take it from there and do the job on its own.
More details will be given as required, depending on the complexity of the design, we may build the prototype ourselves or let the designer build the prototype for us.
