Contest Closed
Hi all, thanks for checking out my contest! I am involved with a company that is looking to receive some entries for a "prototype" electric unicycle. If you aren't familiar let me give you a brief background. Remember the hoverboards last xmas?? The electric unicycle works on essentially the same principle (upside down pendulum theory) to achieve self balancing capability. The current offerings on the market just don't cut it, the plastics are basically thrown together around the requirements of a build, rather than incorporating the necessary components into the design for a smooth finish. I would like the final product to be somewhat futuristic/prototypish looking, maybe a bit sporty. You can get a feeling for whats out there by doing a google search for "electric unicycle". Integral to the design there are 3 requirements. 1.) Obviously the plastic fairing will need to have a cavity for the wheel, but in addition, it will need to subtly include a space for lipo batteries, (doesnt have to be in any particular shape however), and also must include spot for a pcb control board. Both of these items arent excessively large, the PCB is about 4X3 inches and the batteries are about 5X5X1 (but can be reconfigured). 2.) I would also like to incorporate into my design a headlight, and a tail light if possible, but most concerned with head light. Would also like to leave the option open to include small bluetooth speakers, however these would not take very much space at all. 3.) Finally, this design will need to have a retractable handle for balance when getting on/off.
The final concept will be evaluated on how well the designer(s) can incorporate my requirements into the overall finished product. Is it slapped together and designed around the requirements....or rather is it designed from the ground up to conveniently incorporate these added functions....that will be the question I ask when evaluating.*** bonus points if you can cleverly incorporate a "fox" into your design, but not required. If chosen to do so, it will need to be simplistic in order to replicate, but have good taste.
Don't Wants:
a copy of something currently available, with a few changes slapped together. I have included a 2D drawing that I made with the basic principle of what I am looking for, however please incorporate your own style, don't be constrained by my lack thereof.
Ask for Sample:

#12 Unique Electric Unicycle by Prasanth-Designer
I have designed this unicycle with my little thoughts considering the good look, front and back light, space for battery and PCB board. This model is designed in a way for manufacturing feasibility and ease of manufacturing. Kindly give your comments to alter the design.
I'm good at solidworks, for now I have designed in creo and I have included the step file and IGS file with this submission.
Please feel free to leave a message.

#5 Fox Themed Electric Unicycle by TBUSCH
Thank you for taking the time to consider my design. I made the wheel 18" in diameter, which seems to be on the larger end of standard, to accommodate rough terrain. The main housing of the unicycle is design to be made of injection molded plastic. There are sections in the body to hold the battery and the computer controller. Each of these has a cutout with a heat sink that is exposed to the inside of the wheel well. Thus, when the wheel spins it will create a draft of air which will cool the heat sink and thus keep the battery and controller cool. I have mounted the headlights where the fox's eyes would be. The tail lights are just under the fox's tail. I added rubber bumpers to the bottom corners of the housing to protect the plastic.
Best Regards,
Tom Busch

#2 Foxicycle by johannesvds
Good day,
Please find attached my Foxicycle design!
My design completely embraces the fox theme. When looking at the side view one can clearly see the fox head shape and pointed ears.
I have modeled the Foxicycle with one step open and they other closed in order to get an idea of what it would like when used and when being carried or stored.
Lights are mounted on the front and back (modeled in white), in the "ears". They are mounted sub-flush to ensure they don't easily get damaged when the Foxicycle is accidentally dropped.
There is also provision for 4 x speakers on the sides which are also mounted sub-flush. They are modeled in black.
The batteries as well as PCB fits with ease in the head of the fox, they are in the assembly. The easiest way to access the electronics would be by un-clipping the top panel to which the handle is attached.
I am unsure of the size of wheel you would want to use and other electronic parts, but they design can easily be scaled to ensure proper fitment of all necessary equipment. I believe it is the design lines which makes my design unique!
Thanks for reviewing my design and any feedback is welcome!
Kind regards,
Johannes van der Spuy

Just to be specific : you want a few renders of the new design? Just that or you want the SolidWorks file also?
What do you want us to submit : pdf, SolidWorks,etc...?
What is a "fox" could you also provide a picture or even a SolidWorks file of the "fox" please.
What size are the lipo batteries? Also SolidWorks file or atleast .PDF please
PCB Control panel also the same .PDF or SolidWorks if you can.
Thank you for your time

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
Interchangeable frisbee disc design
Hello, 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.

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.
3D CAD Design Of A Dagger
