This clamp joins OpenBeam/Misumi 1515 extrusions at a 90 degree angle.

It is meant for axial and radial loads, it will probably not do a good job for angular loads.

The screws (M3 12mm) are off-center by design for two reasons:  
1) Make it as small as possible  
2) Prevent stress/cracks along the center  

Additional parts needed:

• Recommended mounting: 4x M3 12mm
• Alternative mounting: 2x M3 12mm and 1x M3 8mm

My wife fell in love with http://www.thingiverse.com/thing:256725, but she wanted it made with a stem. So modified the rose from one and resized this stem http://www.thingiverse.com/thing:84075.

A beautiful rose with individual petals and a easy-print, strong stem.

Perfect for Mothers day, Valentines day, or in a nice vase around the home!

3D Printer Superstore will have these roses available for purchase for Mothers day.

Few days ago, i was watching tv and a guy was wearing a 3d printed belt. I felt it was so cool that I wanted to design mine. Here it is!
I am wearing it for sevral days, it is confortable and I didn't get any weakness issue so far.

The closing system is still to be improved to make it easier to use (buckle shouldn't be totally remoable), but it works fine.

The Glaucus, named after the Blue Sea Slug (Glaucus Atlanticus), is an open source soft robotic quadruped from Super-Releaser { http://superreleaser.com }. It is a proof of concept for a method developed at Super-Releaser that can reproduce nearly any geometry modeled on the computer as a seamless silicone skin. The company hopes to apply these same techniques to practical problems in medicine and engineering as the technology develops.

The quadruped has hollow interior chambers that interdigitate with one another. When either of these chambers is pressurized it deforms and bends the structure of the robot. This bending produces the walking motion. It is similar to how a salamander walks, by balancing itself on one pair of legs diagonal from one another while moving the opposite pair forward.

UPDATE 8.16.16 - Glaucus development has been moved to this page https://www.thingiverse.com/thing:1695577 Please refer to it for fabrication details and use its comment threads to post issues and discoveries.

UPDATE 1.17.15 - I've uploaded the body, combined, and internal geometry as stl's so people can download and print bots based on the Glaucus that don't use the same molding.
