Looking for a qualified individual to draft a CAD design for a disc golf disc aka frisbee disc that has a standard center core that can be screwed into exchangeable outer rims. The design must be within specs that I have outlined and feature an air tight interlocking design that will not come loose when the disc is thrown or hits an object. Production of this item would be injection molded with TPE.
Wants:Accuracy of specs outlined, design and feasibility of real world use.
Additional Information1. Diameter: 21.1cm diameter (including core + interchangeable outer ring)
2. Width of outer ring 2.3cm
3. Be within PDGA technical standards (see below)
Disc must not be less than 21 cm in outside disc diameter, nor exceed 30 cm in outside disc diameter;
(4) not exceed 8.3 g per cm of outside disc diameter;
(5) not exceed a maximum weight of 200 g;
(6) have a flight plate that does not exceed 0.5 cm in thickness, including any raised features such as
lettering, ridges, nipples, and other thickened parts. Discs with a thickened section atop or underneath
the flight plate, however, may increase to 1.0 cm in flight plate thickness in this section only, provided
that this section:
(i) is circular in outline;
(ii) is between 5 and 10 cm in diameter for an area with a uniform thickness that is centered on
the center point of the disc; and
(iii) gradually thins from the thickest section with a maximum slope of 60 degrees at the outer
edge at a slope that averages no more than 50% (or 22.5 degrees) relative to the surrounding
part of the flight plate. No part of the underside of the flight plate may be closer than 0.3 cm
0.5 cm to the plane defined by the bottom of the rim.
(7) have a smooth surface on the bottom part of the rim; that is, a surface free of any irregularities such
as protrusions or depressions. When placed on a flat surface, the rim must have no discernible gaps
between itself and the surface on which it is resting.
(8) have a rim area, beyond the top of the flight plate, that does not include any surface elevation that is
more than 3mm above the outermost edge of the flight plate.
(9) have a rim width no greater than 2.6 cm (Does not affect discs approved prior to 1/1/08);
(10) have a circular inner rim no less than 15.8 cm in diameter. (11) have a rim configuration rating of 26.0 or greater;
(12) pass the leading edge radius test with a 1/16" (1.6 mm) radius gauge;
(13) beveled edge design
I have CAD files of existing disc golf discs that have the profile required if necessary

#6 Interchangeable frisbee disc design by Rahul Sharma (RS)
#3 Snap Disc by rlassman
Disc golf disc with a separable core. The core snaps in and out of the rim using lip and grove fastening. The core and the rim should be made with different thermoplastics. I.e. The rim should have a higher tensile modulus than the core, this way as the disc spins centrifugal forces will cause the core to expand more than the rim.

Hard-Hat Clipable Safety Notification System (#2)
We were very happy with the results from our first design concept competition so we decided to host another Cad Crowd competition but focus more on designing to a specific PCB and shape this time. We're looking for small, sleek, manufacurable, and aesthetic designs for a hard-hat clipable safety notification system for construction workers to improve their work safety. The device can sense dangers with internal electronics and alert the user real-time using light and sound notifications. The device will be clipped to the under-side of the hard-hat (see attached image "placement.png"). The device has LEDs along the curved portion of the PCB and two side-fire speakers to convey dangers to the user (see attached image "PCB.png"). There is a snap-dome push button on the right side of the PCB. Please design a fused rubber actuator for the snap-dome. Assembly: The front case will have 3mm screw bosses. The clip slides over the boss, next the PCB, then the back case, then a screw to hold it all together (see attached image "assembly.png") . The project will be pre-payed once there is 3 quality design entries (including CAD files).
Skull And Snake 3D CAD Design
Now that I have your attention I need an awsome 3D CAD Drawing of a Snake & Skull in a high-res STEP Format. It will be used for 3D Printing and also a graphite mold will be produced on a CNC Milling Machine. The mold will be used for casting silver. Attachment 1: Please use this as a guide for the position of the snake on top of the skull. Give as much detail and texture to the skull and snake. The detail of the scales on the snake are important. Attachment 2: A guide to the shape and detail of the skull to follow....... The color of the skull should be off white as on the sample attachment. The snake should have natural colors. I have 7 more interesting designs in the works...... This will be a fun and exciting project. Thanks Robert
Adjustable Serving Tupperware
In theory, this is very basic. Although I am just a law student and by no means an engineer of any sort. My idea is to create a tupperware that has slits in a grid like form on the bottom and sides. Additionally there would be slits under the lid. With the grid-like slits, one would be able to put inserts in order to separate there food. with the insert going into the bottom, sides and the lid, there would be a nice seal from any liquids or foods mixing with the others. Obviously, the point of the grid is to be able to create different sized servings and adjust them from bouncing around. Basically, one could put a perfect compact cup of rice, another for veggies etc. The preserving tupperware current on the market do not allow this and one has to purchase a thousand of them. My vision is for it to be able 10 inches in length with a 5 inch witch and about 2.5 inches tall. The top of the tupperware and lid should look similar to your standard rubbermaid tupperware. the walls of the tupperware should not be less or more than 90 degrees. The corners and need to be rounded. The slits them selves should not be to shallow, for that would defeat the purpose of them. My estimation is that they would be about .5 centimeters. Because of the slits, the bottom and sides could/maybe/should form a ridge like surface. (think of ruffles) Lastly, the ridges, or slits should be continuous, at least in my mind around the entirety of the tupperware, which means the lid will need to account for vertical ridges along the walls of the tupperware and still be able to seal it. Although I will not prepay, being the cautious man of law that I am, payment will be given upon the winner being chosen. AND, in the event that my price is significantly low balled and outrageous I will increase it if no one in their right mind would accept it. Thank you.
