Very basic slide on holder for a Nexus 7 tablet and Nexus S 4G (Sprint variant confirmed working), as well as matching straight, 45, and 90 degree arms for making random setups for the tablet/phone. Can be used for a multitude of rigging setups for just about anything. EDIT:Added Nexus S 4G holder. Printed on a Solidoodle2, the 45 degree arm is 123mm, the rest should be a max of 115mm. I printed solid infill to make sure I didn't get a concussion, they are pretty sturdy. None have been through Netfabb, but printed fine on mine with Skeinforge/Pronterface. A 'base' needs to be made to attach this to. Using SketchUp, the two holes need to be 18mm apart in the middle, and 2.5mm in radius (my measurements, at least). I made one that fits with friction over my headboard, and it works just fine, as seen in the picture.It can be glued, or screwed together using 3/16th bolts and wing nuts (wing nuts not necessary for the arms, the 2.5mm hole makes a very firm grip).I will mark this as a work in progress until I have a functioning multiple use clamp, as well as some other more interesting arms.
