Description:The spiral of learning (Kolb & Kolb) is a simple helix visualising the learner's progress. I need to visualise a more complex spiral. Turns on this helix are circular. Each turn represents an interaction between teacher and learner. This helix contains 1 grand turn. A grand turn contains at least 3 smaller turns. This creates a turn complex. Each turn achieves a small or large rise on the z axis depending on the diameter of the turns on the x and y axes. In elevation view the turn complex should have a stepped appearance due to the presence of the smaller turns, with the lowest steps at left and the highest at right. The idea to be communicated is that the larger turns contain at least 3-5 smaller turns. Each turn achieves a small increase in z-height as the learner exits the turn, like freeway traffic using a cloverleaf junction. Multiple interactive turns aggregate to a large gain in z-height. In the attached illustration, the largest loop should be understood as not a part of the visualisation. I would like to see two variations of the design:
(1) smaller turns ranged on outside of grand turn diameter
(2) smaller turns ranged on inside of grand turn diameter.
Wants:The structure is of 'sheet metal' form with a minimal sheet thickness and ribbon-like form factor. Blue semi-transparent material is preferred to reflective metallic material, so that overlaps and crossings are salient. It can be manipulated in 3-space using display software, or at least displayed as an animation of prerecorded rotations, eg, from plan to elevation view and back to plan view. The model can be output in different orientations and magnifications as a 300 dpi PNG or JPG illustration.
Don't Wants:3D printing, machining or physical production. This is a virtual object for the visual representation of a pedagogic concept. It does not have to conform to any engineering or manufacturing standards.

3D modeling of a J-shaped massage tool, much like a Theracane only smaller in dimensions. The tool should be modeled as close as possible to the attached images. The straight portion of the J-shape is approximately 10 inches long and 3/8in in diameter. The hook portion of the tool should form an approximately 180 degree arc and terminate in spherical end of 9/16in diameter. The handle, at the top of the J-shape, should be approximately 3/4in in diameter. The attached jpg images are of the actual tool that I would like modeled and should give you a good idea of it's dimensions. The png file should also provide a good reference. Thanks.

Design should be of a liver shell. It should be an anatomically accurate model that can be printed if needed to. The inside should be hallow and the liver should include a hole on top where the hyper-vein would normally be and a hole on bottom where the vein would leave. The liver shell should be a 2 piece design that can be clicked/ screwed together to symmetrically put together the 2 halves. http://www.exchange3d.com/3D-Model-of-Liver-Anatomy/prod_28235.html#preview A more simplified version of this will be perfect.
Mechanical Engineer to develop light guides or light pipes used with LEDs
Looking for an engineer that has experience with light guides or light pipes used with LEDs, and that can design a few simple light guides for an electronic device. 3 LEDs - red, green, blue will feed the light pipe. the other end of the light pipe will be visible to the user thorugh a cutout in the enclosure. the user will see this end of the light pipe, which is 2 strips each at .2 wide x 2" long. there may be some curvature to these 2" long strips (maybe a radius of 2.5"). when the red LED is on the strips will light up red. same for green, etc. need to make sure the lighting is continuous (not brighter at one end than the other). Proven experience with LIght pipes is required. $100 for initial sketch and background proving that this design will work. Further work would then be given to winner to develop the concept into a injection molded part. Good Luck and I look forward to working with you.
This is a prototype of a wall angle, I need autocad drawings to manufacture this piece.
