What kind of molding process do you prefer, sand casting, permanent mold casting or die casting?

Thank you for your questions.
For all measurements please stick to the drawing.
The photos represents only a rough model to have an idea how the bracket should look like and to make first tests over satellite.
The transceiver (in the document called ETRIA) shall not move, tolerance of its position should be about +/- 0.5 mm.
The feedarm is steel and does not move through the ETRIA weight. The final product in mass production will be made of molded Aluminum or similar metal. So it will be stable.
The 3D printed model is for testing and optimizing of the position based on real measurement over satellite.
This is the reason why I would need to modify the position of the E TRIA in a range of +/- 1 cm. The adapter shall not be adjustable, I would do the modification on the CAD drawing and print the modified adapter until the antenna reaches its desired performance.

I'd second Rayeed's question.

In addition, since this appears to be a mm-wave to cm-wave part, do you have acceptable tolerances for eTRIA deflection under load from gravity at different angles, especially at 0 degrees elevation? 3D-printed structural parts can be difficult, or impossible to simulate accurately.

What do you mean by "position in the CAD drawing"? Would you like the adapter to be adjustable in the field, or would you simply like to specify the exact critical dimensions of the part yourself?

Is the software requirement (123D Design) flexible? Would other Autodesk software be permissible?

Finally, are you planning to produce all of the units for deployment with 3D printing methods (I am assuming fused deposition modeling, FDM)?

Rayeed, you are correct. My model does not look like the side profile of the pics the buyer submitted. It's much higher than that.
Thomas can you clarify ?

Just to clarify, your drawing has the tube section up much higher above the angled brackets than your photo depicts.
Do you want to stick with the drawing dimensions ?

Prosthetic Cover Design
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: http://unyq.com/prosthetic-covers/unyq-armor-below-knee-covers/ http://www.alleles.ca/leg-covers/ Here is an image of a prosthetic that does not have a cover on: http://jdeorthotistandprosthetist.co.za/wp-content/uploads/2015/08/FullSizeRender-4.jpg
Human Skull Masterpiece - STL for 3D Printing
Hello, I am an artist living in NYC and like so many artists, I am fascinated by the human skull. Long before Damian Hirst made his diamond encrusted skull, I made pilgrimages to the Metropolitan Museum of Art to look at the Holy-Grail of all skulls. The skull below was made in 17th century Germany and was carved from ivory. The softness and detail is extraordinary. More importantly, the surface is irregular. Its edges are imperfect, just as a real human skull would look after it is dug up from a grave. It is a masterpiece. It is anatomically perfect and it has an emotional gravity that is captivating. (Fortunately, ivory is banned but I also want to make a skull of my own, hence 3D printing.) Check it out here: [url=http://www.metmuseum.org/collections/search-the-collections/120023910?rpp=20&pg=1&ft=Ivory+skull&img=1#fullscreen] http://www.metmuseum.org/collections/search-the-collections/ 120023910?rpp=20&pg=1&ft=Ivory+skull&img=1#fulls creen[/url] A bit futher down in quality from the perfect ivory carving at the Met are the porcelain skulls by Nymphenburg. I love the hand painted flowers and insects on them but, more importantly, I love the negative space in the jawbone, namely, the slightly opened mouth and missing teeth. As much as I love the Nymphenburg skulls, they are way too expensive and are a bit too pretty for me. They don't have the psychological weight that the ivory skull from the Met has. What I would love to do is create my own ceramic human skull using 3D printing. I would like the skull to be around 4" in height and around 6" at its deepest diameter. I would like it to be anatomically perfect inside and out. No detail left out. I wonder if it is possible through 3D printing to match or even exceed the perfection of the ivory skull at the Met but also whittle away at the 3D model to a perfect imperfection. Ceramic would give the skull a visual richness and a heft that plastic does not have. Also, if a few skulls could be made, I could paint my own insect world on them. Finally, I have included a Human Skull Anatomy Chart. It is quite exhaustive. I am sure a real human skull can be used to make the initial 3D model but any model would have to be as exacting as this chart. I would love to create a 3D skull that is indistingishable from a real human skull, only in mininature. I hope to get some interest from all of you. This contest can be tough. It would require getting a real human skull and doing a 3D scan of it. Then, once it's scanned, the artistry of the designer would take over; such as paying attention to the postive and negative space in the design, the details, and the imperfections that happen over time with a real skull that has been buried. I hope you all can come through for me. Thanks.
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.
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
