#16 E TRIA Bracket by Miqdad Mazlan
I have taken all the considerations into the design and produced a bracket that can be 3D printed for testing. In the part file itself, the dimensions can be modified and adjusted to achieve the optimal position. The bracket can be caste out of aluminium or steel whichever you prefer.
If there are any other considerations, feel free to ask!

#10 TOOWAY E TRIA Bracket Casting by Brandon C
This is a cast aluminum design for the bracket. It is lightweight (.42 kg) and sturdy enough to withstand gusts of wind more than sheetmetal. You should be able to 3D print this part without issues

#13 Tooway E TRIA 98 Bracket by Ridwan Sept
" Tooway E TRIA 98 Bracket "
I create this models based on
- Stable models
This bend has many models , so with this the models will more strong and stable enough to hold 2 kg loading assumption . ( Please check the attached files , I did the simulation process and this strength models are strong enough to hold the 2 kg or more loads ) .
- Look
I tried to add some art and safety value in this models. With this bends the models look more elegance and I add the files to every corner radius to Increase the safety value when we assembly it . We can use as powder coating metal finishing process .
- Simple and Easy to Production
I used Staimping this process to mass pro models . So we will get the more inexpensive production costs more easy to production .
Please give me your comments .
Thanks ,

I would recommend you to use either galvanized steel or any steel with some sort of electro-coating (to protect from the environment) instead of steel.

This is not a 3d print friendly design, but in terms of simplicity and production costs I don't think it could get better then this. I used elongated holes so it permits small adjustment on one axis. If you really want to 3d print it I can make a solid part out of it maintaining the position of key elements.

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 ?

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 ( 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.
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: Here is an image of a prosthetic that does not have a cover on:
