We need you to take our design from being just a sketch in Paint, to being a 3d model with the correct dimensions and specifications. We need you to determine how thick the plastic would need to be to resist breaking, how tall the box needs to be. You will need to have standard sized cards to use to measure, as there are some requirements that require you to fit certain numbers of cards into each compartment. You will need to measure and make the lids the right lengths, and you will need to make it clear to a plastic manufacturer the process to make this product. In each of the top and bottom lid, it will need to leave a space that a single card can slide into so that it is visible through the lid. The entire plastic box will be a transparent color, but the covering over just the single card in the lid will be a clear plastic so that the card is perfectly visible and the color isn't distorted. Making a box with a few compartmental lids, should be pretty easy for a product designer. ...

I would like to create a glow paint using strontium aluminate particles ranging in size from about 20 - 50 microns. You can read up on strontium aluminate and will find that there are several supplies for this material. The particles are dense and will quickly settle in clear medium such as urethanes, etc...This creates a problem during storage as the particles will cake on the bottom of a container and they are difficult to re-suspend. I have had success mixing the particles with two part epoxies. It is useful in some circumstances, but it's really not suitable for painting because it is too viscous. I believe I need an anti-settling / thixotropic agent. But, I haven't had very much luck being able to identify exactly what I need. For this project, I need someone to recommend a way to formulate a paint that could be used with strontium aluminate (glow) particles. Ultimately, I would need you to supply me with links / vendors for materials so I can purchase what I need. Here's the...

I am in need of an exterior design for a single family residence. This is concept only at this time, although I may come back in the future for a floor plan. I will give more details (lot measurements, pictures of neighborhood, etc) once I hire for this project, although here are some rough guidelines: -Square footage needs to be around 4000 total -Two or two and a half stories tall -Needs to fit in well with the street (I will provide images of the street and houses) -Maximum foot print of the house is around 2200 sq ft -We need basic dimensions, but most importantly very high quality renderings/3d modeling of the structure -We have a pretty quick turnaround time. I would need completed drawings in around 3 days from time of hire. I will reiterate.....this requires no work on the inside, no floor plan, no interior design. This also does not require an planning for construction. I simply need nice exterior images of what this site could be so that we can determine how to proceed w...

Hi - We need proper engineer drawings and Solidworks files made of a sheet metal enclosure. The enclosure is essentially a 20" x 12" x 12" box with rounded corners along one direction and some holes. We have solidworks for the file as detailed for other plastics processes but not for sheet metal. You'll have to break it up into pieces (if needed) and/or provide welding plans. And you'll have to optimize it so that it's as easy to make as possible and doesn't require much labor. Requirements: 1- Solidworks user 2- Must have significant experience with sheet metal design and fabrication. You must actually have completed sheet metal projects you can show us. 3- Fast turn-around. Optional but good to have: 1- Connections to actual sheet metal fabricators. Thank you

We are a new company established to bring to market an innovative concept of a connected device. We have built a first prototype including electronics and smartphone app and are now moving to the next step, object of this job. The goal is to create a connected fitness device that is made of 3 parts: - a part hosting the electronics (the electronics itself is not included in this job) - an inflatable part over a plastic frame - a flexible arm linking the 2 parts I have made a first 3D prototype of those 3 parts and will provide the .STL files. The job consists in designing the 3 parts, including the way the parts are attached together. The bidder must be in the San Francisco Bay Area as face-to-face meetings are expected to be necessary. The bidder is also expected to sign a confidentiality clause for this job, above and beyond the default Elance clauses.
