HI,
I think electric motor should not be mounted directly on the cover, because there will be sag.
You can use standart wheels or remove them at all.
If you use a propeller that I send you, I can draw attachment to the axes of the propellers
If you have any requirements, please write me

Thanks Alen,
1. Normally, the designer is supposed to make sure there is a vent at the top of the tank that will help in preventing vacuum formation and tank collapse.

2. 4mm Stainless steel. No other material

3. Flat reinforced concrete.

4. DN80.

Questions:
- Is there a possibility of a vacuum in this tank (like, if all molasses would run out from the bottom of the tank, while none molasses (or air) would enter in it, so under-pressure would be created in the tank)?
- Do you need tank to be made out of stainless steel or is there some other material allowable?
- On what kind of surface do you plan to place the tank (flat concrete, special foundation, or something else)?
- How large inlet / outlet pipe for molasses and inlet pipe for water do you need?

1. Molasses will first be metered into the mixing tank or allowed to flow by gravity from a day tank (The Designer should make provision for a stainless steel graduated steel bar permanently fixed inside the tank for measuring volume) then water will be admitted into the tank until the required volume is attained while stirring continuously.

2. The visual access will be via a manhole at the top of the tank.

3. The fluid will be mixed at ambient temperature

Best regards,

I have a few questions:
> How are the two fluids to be mixed?
> Do you need visual access to the mixed fluid?
> At what temperature is the mixed fluid to be kept at?

UAV designs
I am looking for a design on an unmanned aircraft which will have a flight time of over 1hr. It must be able to carry a weight of 7kg and a camera. I know there are loads of uav's on the market so if someone can come up with the 3D plans that then can be made to a working model. I am looking along similar lines as the scan eagle etc. The best design may possibly lead to a private agreement to design a helicopter also.
Toy Stroller
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.
MuTT MoTE™ and MeOw MoTe™
Very simple stackable design for a pet feeder with the food in the middle and a mote of water around it. Center should be high enough to keep food dry and surrounding water mote area should be large and deep enough to hold enough water for the pet to drink.
De Laval Nozzle
A De Laval nozzle for supersonic kinetic spraying.
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.
