Dual sided Shampoo/Conditioner bottle

The case will be 2 parts. A top and a bottom. We'll use this design as the basis for a case we plan to manufacture. See attachments for dimensions and measurements. The design should be able to easily scale to fit both the 13" and 15" models, but the 15" is our priority. You must have a retina Macbook to determine the exact curve of the case and to make sure there are holes on the sides near the bottom for the vents (http://images.anandtech.com/reviews/mac/rMBP13/DSC_8944.jpg) These cases are both similar to what we're looking for: http://www.amazon.com/Speck-Products-SeeThru-MacBook-SPK-A2411/dp/B00937DLE8/ http://www.amazon.com/keyboard-15-inch-MacBook-15-4-inch-Display/dp/B008NSA3OY/ Any of the following file formats are acceptable: .stl .3ds .dae .blend

To design a plastic fitness step. Stackable. Unique design. Include logo on both sides See attached pictures of similar. Able to take a minimum 100 Kilograms

We are looking for some concept sketches for a key case. An innovative key case design which can hold a typical car key (attached picture). The case itself should be able to fit on a key ring. The key should be completely hidden inside the case until the case is opened (by some creative means or mechanism) to reveal the key, either in whole or part – at least, so the user can press the buttons on the key itself. We are looking for a high-end, upscale design, which combines smooth-functionality with luxury and desirability. A pleasure to look and feel, a pleasure to simply hold in your hand. A status object and a pleasure to use, again & again - perhaps damped - with an extremely desirable finish, perhaps piano black, brushed steel or rose gold ... following an interface design associated with the modern iPhone-types. However all design finishes will be considered.

We are a new venture specializing in the creation of Self-Heating Tumblers. Our tumblers (travel mugs) are quality made with precision and self-heat themselves by the press of a button. The button initiate a reaction inside the tumbler chambers, causing the interior to heat up. We are looking for a concept/prototype design in 3D. We have attached design specifications and photos describing the product.

The goal of this project is to find the most efficient engineering solution for the pump in a hard plastic bottle. The bottle itself is going to be made of hard plastic or glass, so it will not be possible to squeeze the bottle itself to squeeze the shampoo or conditioner out. If the shampoo is required to be pumped out, the bottle will have to be tilted with the shampoo side down and pumped air will help the shampoo to flow out. So the size of the pump have to be enough to provide enough pressure for the liquid to be pushed. We don't want people pressing 10 times on the button before they see any effect. The pump will have to be an air pump as it will work for both chambers with different liquids and they can't mix. The pump will either twist to the chamber that requires pumping or the 'locking button' will unlock the inlet that will allow the air to be pumped in OR another innovative solution offered by engineers/product designers. PLEASE NOTE: There must be something preventing the shampoo and conditioner to flow out of chambers, some sort of valve or another engineering solution. For example if the inlet for shampoo will be unlocked while the shampoo side is facing up, the shampoo should not leak out. The manufacturing cost is a very important factor. The less parts will need to be manufactured to assemble the product the better. Simplicity and cost effectiveness of the design is a key. If the design submitted is exactly what is needed then the designer will be asked to help us to finalise the product until it is in manufacturing. Please use software that would allow us to print a 3d model.
