This is an all plastic bearing using 6mm AirSoft BBs

Four of these are used to pre-register the alignment of the NextEngine 3D Laser Scanner HD when doing long linear scans. Designed to hold LED laser cross hair modules aligned in such a way as to produce a laser square outlining the scanning envelope. They are attached to an 80/20 strut frame work, see -

This 3D Terrain/Topographical Model was done as a gift. Software used was Google Earth to find the earth coordinates, NED/DEM maps were ordered from MapMart.com (these people were very helpful), then Global Mapper 11 converted the NED/DEM maps into a .STL format (single layer of triangles) which was converted into a 20mm thick 3D model using ArtSoft-3d, Magics RP was used to cleanup and cut out the property along the deeds boundary lines.

As the name implies - it holds pens (specifically Sharpies and PILOT V Razor Point). I got tired of having pens rolling all over my desktop so out comes RapidWorks and I draft up a parametric model, convert to mesh and save out as .STL file and print it.

This is a dream come true -
need something, dream it, design it, 3D Print it ...
it will never end now ...

I also came up with a supply of build material at half the the price I was paying for Stratasys build materials !!! this is a BIG find !!!
thanks johnnyr

You all might find MiniMagics helpful in viewing .STL files.

This is a simple 2 inch hinge (both halves)
I was inspired by jrombousky's Hinge thingiverse.com/thing:1358

Coaster to put chilled wine or other beverage bottles on so they don't leave a sweat ring on the table.

I couldn't wait for UPS delivery so I used Rapidform's XOR to make a parametric model and then 3D printed up a set.

I designed these as four sided pyramids with a .75" through hole so I could insert 3/4" PVC or Black pipe, can't do this with three sided pyramids unless you use equal length pipes - not really adjustable.

Added three sided pyramid for comparison.

I printed these up 5.53 hours. Assembled with no tools - way fun way to use up the last bit of ABS black I had in an old cartridge !
I think I could have printed the set as a single piece instead of 28 .STLs on a single platen (chain would have been different, and I could get away with it because I use H2O soluble support material)

Printing Testpart for RepRap Machines by Patrick

We as a community of "fabbers" need to have some sort of standard to gauge how our machines tolerances are evolving, Patric has made a good start.

These are MakeBeam 10cm prototype .STL files that have been run through "Magics 14 64bit" to remove all kinds of errors and make play nice with the majority of 3D printers throughout the world... (courtesy of Materialise)
I've included a 254mm (10") for yucks (if you print on a Dimension - wrap it with support material otherwise it will bend on you ...)

Note: as a curiosity I made a horizontal an a vertical lay/orientation - and as you would guess the horizontal is a lot stronger. If I had unlimited funds, it would be interesting to do real testing to see at which orientation (90, 60, 45, 15, 0 with rotation components also - permutations get astronomical), would be best to build for overall beam performance verses maximizing in a single plane of force (vertical lay/orientation with no side forces would win hands down, compression load only)

This is the turret for the conversion of a Tamiya 1:16 scale KV-1 tank to a JS-2 tank. The upper hull and glacius plate will soon follow.
