Contest Ended, Winner(s) have been selected.
Description:
We are looking for CAD designs for coverings for prosthetic legs. The products are generally around 450mm tall, with a proportional width similar to human dimensions. We are specifically looking for interesting aesthetic designs.
We are open to any type of style, but it should be designed to be structurally sound. It will not have to bear weight, but will have to stand up to bumps and knocks. The final print material has not been specified, but you should assume it is an FDM print.
Your design should include some method of attaching the cover to the prosthetic.
The product will be printed in a single colour so if your design has multiple colours it will need to designed in such a way that it's easy to paint the required parts.
We intend to create a range of covers so there may be ongoing work for the successful designer(s)
You should supply us with a CAD file, ready for us to setup in Grasshopper for parametric modelling.
You can find examples of other similar products here:

#50 Generative Lattice design
by Ajay Prabith Prakash
Generative Lattice design makes the prosthetic leg cover Extremely light and strong making it modular.
Unlike other Prosthetic leg attachment this is magnetically fitted rather than an old school strap system.
All the Details are provided in the Assembly view. For more details please feel free to contact me.
Thanks for the opportunity.

The concept looks and feel:
The structure: An elegant crossing Ribbon geometric pattern that bonds around the leg.
The inner space of this diamond shape holes is replaced with another geometric pattern that follows the geometric theme.
The idea is that we have different inner patterns with tailor made paneling design according to client request.
This creates a custom design for each user.
The functionality concept: Attachment to the shaft
I created a simple elastic part (made rubber hollow band) with specific round shape that can stretch and grabs the shaft like an o-ring. Attached to specific holes in the hard cover, like Flip flop shoes, on the outside the this part closes up by an elastic hop. The idea is that this part can have different colors to give you another custom feature.
Hope you like it . Will try to send a couple more concept I'm still working on.

by Bryce Allen
THIS PROSTHETIC COVER IS DESIGNED TO FIT ANY LIMB. USING TWO BOLTS AT THE ANKLE AND A PAIR OF CUPS, THIS SIMPLE GRASP CAN BE INSTANTLY TAILORED TO SUIT ANY ARRANGEMENT. DESIGNED TO CLOSELY RESEMBLE THE HUMAN LEG, THIS DESIGN DELIVERS A SIMPLE AND CLEAN LOOK TO THE WEARER. A ROW OF SYMETRICAL BREATHING HOLES DELIVER A SHARP APPEARANCE. THIS CONSERVATIVE SHARPNESS IS THE "SILVER WATCH" OF PROSTHETIC COVERS. IT'S A CLASSIC LOOK THAT WILL NOT MAKE ONE FEEL AMBARASSED TO WEAR- UNLIKE OTHER OVERBLOWN DESIGNS THAT SEEM TO MOCK THE DISABILITY. FOR SOMEONE THAT WANTS SOMETHING THAT IS SIMPLE, STRONG, AND RELIABLY EASY TO USE- THIS IS A PERFECT SOLUTION.

#57 Forgotten Hero 1
by Richard Simpson
The design concept is to honour the difficult lives people with disabilities live with. The Forgotten Hero 1 for example may honour the lives soldiers led and depict the hardships they went through.
This prosthetic cover is designed by using human leg anatomy drawings as reference. It is designed to be aesthetically pleasing, ergonomic and interesting. The cover consists of two halves that clip into each other around the cylindrical structural member in the centre. There is a top and bottom mechanism which is pressed to unclip the two halves.
It can be printed and painted or printed in different colours and materials with 3D printers like Stratasys J750.
The Forgotten Hero 1 will be the first of more in the Hero Series of Prosthetic covers.

by KP HARISANKAR
Kindly note that parts mentioned in model as 'nut clips' are not to be 3d printed. Those are for illustration purpose only. Nut clips are easily available in the market. I have used M3 bolts for fastening purposes , so M3 nut clips are to be utilised. Those Nut clips can be easily attached to the front cover using adhesives.

by Omar Farouk
this is just version 1 and i want your impression sir it's very editable
in this version i made it as a one piece
as for the method of fixation the cover will have two polyethylene straps with metal hooks that allows you to pull and torque it into place as well as make it easy to remove if you choose
in version 2 i will design a different method of fixation which is a 4 small screws but the Prosthetic Cover will be 2 pieces
as for the appearance, well we can play with it as much as we want
please sir rate me and tell me if you want any modification

by Omar Farouk
this is version 2 as promised, as i said before we can play as much as we want with the appearances and colors, this version is way more rigid and stable than version 1, it consists of 2 pieces tied together with ordinary thin nuts and socket head cap screws ( the standard number of each is provided in the attachment file in 3 different standards CSN, DIN, and ISO) Assembly drawing is also provided with a video animation to how it's tied together.
i want your impression and please if you need any edit just till me and i'll do it gladly

Hi all,
It must be remembered that it is a design to fight and strike and it is not with 0.5 mm that we will be hit!
Good luck to everyone !

Hi all, Thanks for the great entries. We will review them all and make a decision early next week.
Additional improvement that would need to be considered for most designs above ('including some of mine) would be, a way of prevent rotation and slipping around the pylon when the prosthetic cover is knocked. I have a simple solution that would work with several of the proposed designs with a clamp like design rather than a rubber band, if you are interested. Once you have chosen your design, I would be happy to share the idea, regardless of who you chose to win.
I'd really like to see some more lattice type structures proposed if anyone is interested.
Below knee for now thanks
Hi
You are looking for Ak or Bk prosthetic covers?

Hi KP,
You should size for standard European/American dimensions. The cover will be scaled for different individuals.

HI. In which country are you aiming to sell the product? If we get to know the anthropometry and percentile of body measurements, it will be easy for us to design. For a person with a height of 175cm, prosthetic cover of 450mm will cover his knee region too.
Submitted design, suggest me, If any modifications required.
Hi ,
Now it's clear for me
Now it's clear for me
Hi Justin,
Manufacturing process not yet confirmed. Most likely will be FDM, but possible we could go with SLS. If FDM, we would like tolerances to be wide to allow for wider nozzle, but will to compromise for the right design. Printing with two nozzle sizes is also a possibility to allow for finer detail on closures. Perhaps submit two versions, one with fine tolerance, and one with wide?

Hi Chris thanks for that, do you know what tolerances your machine can print to, just so I can make sure the opening and close features work properly.
Thanks, Justin
Thanks, Justin
The attachment system does not have to be 3d printed.
Hi REDA,
Sorry I'm not clear what your question means? Rates for what?
Sorry I'm not clear what your question means? Rates for what?
??? It takes rates so I know what you need exactly
Hi Justin,
The length of the pylon and distance from knee is dictated by how much of the leg remains, so will be different in every case.
Generally, I would say the pylon will be at least 100mm long.
Hope that helps.

Hi Chris,
Trying to design a reliable fixing method. I have something in mind I am working on, but just need to know a little more about the prosthetic, ie. How tall is the 'pylon'? how far below the knee does it start etc.
Do you have a technical drawing of the prosethic, even if it is a generic one?
Thanks,
Justin

Additional information: the design needs a way to be put on and off the pylon. This means it must be easily removable. It won't be able to slip over the foot or socket so generally this means some kind of opening flexibility or mechanism to allow it to be attached and removed.
International standards for prosthetics tubes is 34mm HD, 30 mm Std, 22mm juvenile. So for this project I would suggest a target size of 30-34mm
Yes I will get those dimensions. The best option would be for the cover to connect to the 'pylon' which is the metal pole between the socket and foot. This is the most standard component across prosthetics. The socket that fits around the limb can have massive variance so probably isn't a good point of point of attachment.

Underwater Drone
I would like to design a deep water drone that can reach the bottom of a lake. The drone will be roughly 2.5 feet long by 2 feet high by 1/2 foot wide. It will have an infra-red camera in front and a propeller in the back.
MACK TITAN TRUCK 1/87 scale down
I need a CAD file for 3D printing conception of miniature model truck resin kit scale down to 1/87 scale,components must have parts for building model kit, cab ,driver seat,frame body and wheels.
Hyperloop Concept Model
I need a concept design and 3D printing ready files (STL) for a Hyperloop Pod.
The design should be inspired by the concept images attached.
The design may be different from this concept drawing but follow the general inspiration of the concept. Creativity is still appreciated.
The doors on the model should be closed. Interior features such as seats are not required.
The compressor fan should be included and detailed. Please also include smaller air outlet at the back of the pod.
The “air bearing” or feet should be included.
The model should be scaled to be roughly 35mm in diameter and 250mm in length.
For further information on the concept and inspiration see attached PDF file. “Hyperloop Alpha”
This is for non-commercial purposes.
The final files should be free of flaws and read to be 3D printed.
I am flexible on software used. I need the CAD file and STL file as a deliverable
3D Model of Small Gold Plant
I need a 3D model of a small scale gold plant. I intend to 3D print the model. There are 5 distinct components that need to be modeled:
1- the crushing module (http://www.mbmmllc.com/product/jaw-crusher-modules/)
2- the hopper module
3- the hammer mill (duplicated X2)
4- chutes (duplicated X2)
5- shaker table (duplicated X4)
I am attaching a plant layout as well as real life pictures of the components. I need a quick turnaround for the design. It needs to be detailed enough for the modules to resemble the real life components, however, it doesn't need to be overly detailed.
