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.

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.

I would like to design a more moden hideaway for guinea pig, hamsters, rabbit etc. I would like to keep still wood pine house since these animals will bite it up. I would like it to be more of a luxury look but still in the same sizing because most customers will buy a small starter cage to fit it in. I will post an example in the pictures of sizing of cage. Guinea Pigs have an issue pulling there food and water bowls in there hide aways and spill everything. I would like the food and water bowls to be attached to the house with a bowl holder where I can remove the bowls on and off to fill up. I would like the food and water bowl to be ceramic. A window can be made where the animal sticks there head out the window to the bowl drink and eat the food easily while inside there home. Attached are pictures of a hideway would like it around that same size. Food and water bowl would like it to be more that shape. Animal Cage picture the hide away would have to fit in that cage size.

I need 3D printable design files and renderings through several iterations of the prototype. Full description of project here: https://docs.google.com/document/d/1_80bHOw9VE4D6vrhBTcpgVaaQoOdOzL2S-REGRjD01I/edit?usp=sharing

We are looking to develop product design drawings to be used for manufacturing of our motion tracker unit, which will be launched for a fitness center chain, for tracking use of exercise machines. The unit will house our own electronic module and battery, so the design shall result in the required 3D production drawings for plastic molding of the unit housing (stp or dwg file format), which will be in two parts (top + bottom), and a matching holder. Detailed descriptions (dimensions and considerations) are enclosed in a separate document, to be considered as guidelines with some freedom for the designer.
