Description:
We are designing a thick gauge aluminum mailbox (0.080” aluminum (2024 or similar) front and back; ¼” (6061 or similar) lid). We are having problems finding an off-the-shelf hinge for the lid that meets our evaluation criteria (below). Lid is a thick, flat piece of aluminum, no bends. Final product will be powder-coated.
Wants:
1. slow-close hinge action required but doesn't force lid to "stay-open".
2. hinge should operate between -30c and +40c, corrosion resistant, aluminum.
3. Be able to affix to our 1/4" thick aluminum lid with either blind-tapped holes or weld in place (assuming heat from weld doesn't damage hinge).
4. be an elegant solution, requiring minimum manufacturing procedures.
5. Lid is angled down to front at 65 degrees from back of box - hinge needs to operate within full 115 degree range.
6. Hinge can't bump lid into wall or box when open - box will be mounted with 0.5" bump-out from wall
7. be a cost-sensitive solution to help keep overall costs down
8. off-the-shelf solutions preferred
Software:
  1. SolidWorks (2016)

Sorry for the late posting - I just uploaded drawings of the mailboxes. One is portrait, the other landscape. Hope this helps in finding the right solution.

What is length and breath of the lid? It is required to calculate the weight of lid.
Are there any limitation on overall dimensions of hinge? I understand you prefer
Off-the-shelf product. Would you throw some light on any type of hinge, that has
been already used by, but not to your satisfaction

Dwarven Forge Bracelet
A bracelet design to complement our long standing line of Dungeons and Dragons/fantasy rpg terrain. Please view our website -- dwarvenforge.com -- to develop a sense for our product. You can also look at our recent Kickstarter campaign -- http://www.kickstarter.com/projects/1745470388/1826778276?token=2a7841d2 (see "Game Tiles" on kickstarter.com). I'd start with a bangle, probably with one main charm, a small crystal and a small charm with our logo -- kind of like "Alex & Ani" level of complexity, but for gamers. The main charm should probably be metal. The bracelets are for women, gamers or partners of gamers.
Spa/health club annex
Convert a 2D, basic floor plan of spa/health facility into a 3D floor plan of spa/health facility. The project will require some creative adjustments to accentuate the look and feel of the facility to align with a spa-like environment. The addition of furniture items typical to spa/health settings will be required. This is a concept project and dimensions may change in the future as the project develops. The final objective/goal is a 3D model that can be used to confirm final dimensions, details, and other information with a larger stakeholder group as the project develops to a final stage of execution.
Solidworks Car model
I am looking for someone to model in solidworks a replica of a car already on the market. I like super cars and classic cars! The file needs to be somewhat editable in solidworks and renderable in keyshot. The contest is quite open ended, the more detail the better.
Exercise Equipment Storage Solutions
We have a number of products which are sold to commercial gyms. They desire storage solutions for these items that take up minimal footprint int he building but maximize storage. I have attached a file with photos of existing storage solutions on the market and also the type of items we need to store in the gyms. We want the units to be modular so they can expand for more equipment as needed. We want the units to be multifunctional storing more than one type of equipment if possible.
Motion sensor
This project is to design the housing for a motion detector for commercial office buildings. it should be approximately 2.5-3.0 inch circle and the body should be no more than 1.0 inch thick. the circle can be bigger if the edges sweep out to with a nice curve back to the ceiling surface. it will mount to a standard t-bar ceiling grid. (the kind of ceiling with the drop in tiles) it should mount in the corner of a light fixture with a portion of the "top" or up facing side exposed to the light fixture. and have a window on the top that looks up at the light... (for a light sensor) the window shall be rectangle and dimensions are: 33.0×10.8mm. the face which points to the room shall have a PIR lens (like this one http://www.jvs.de/Carclo_Fresnel/Drawings/PF68_12076_Drawing.pdf i'd like to receive drawings that are 3d printer ready. ease of mass production and tooling should be considered. drawings should also be open for editing by our team. Our team will add the holders, screws, clips, etc for the Electronics inside. the mounting method could be a small piece of spring steel or plastic.
