ipad in otterbox clamp set for the ipad car cinema thing. Drawn in Vectorworks 2010, so source files can be made available, but may not be useful to many.a derivative of the car cinema ipad holder, so that the ipad rev 1 in an otterbox can be held with the same idea. Use parts ABC from the original , and print 1 copy of the replacement arms. I have also made up an M4 wingnut to assist with tightening the clamp bolt. I needed to ream the 4 Ø10mm holes slightly but the nut traps, the M4's and the slot and tag, and the overall fit is pretty good straight off the plan.
