Self-heating Tumbler Design

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

I am looking for an innovative well designed 7 day pill organizer. I want a design that will stand out visually and must be functional. Pills need to stay in each compartment so they don't fall out when moving/traveling and keep them airtight. Refilling of the 7 compartments needs to be easy to do and not complicated. Materials must be durable and able to withstand daily use. This is for an end user with style. File Format Required - .obj, .wrl or .stl

This is about a first product draft, which shall later be turned into a production ready design. I need an enclosure for a custom made electronic part. The rough form-factor should be similar to a navigation system (see attached files) with a display in front and parallel enclosure boundaries, slightly rounded edges. The display is 4.3 inches wide (see technical details attached) and should be included in the rendering. The enclosure should be 4 cm deep. As a bonus, the display shows attached bar diagram. At the back, there should be the possibility for a DIN rail mount, top hat rail EN 50022 – 35 × 7.5 but also for direct wall mount using screws or mounting to a bar with cable ties. At the front left side of the enclosure, I need a C14 inlet to add a power cable and a Schuko socket: https://en.wikipedia.org/wiki/Schuko or CEE 7/3 socket. See attached figure of the design. The material should be dark grey with a bit reflective surface. Please add our logo to the upper left corner of the front, below the display. If it fits optically, it could glow a bit in green.
