I was inspired by windybut's version (http://www.thingiverse.com/thing:372798) to design my own so that it could be printed on my printer (maximum x/y is 185mm). I have not yet flown this design, so I can't attest to the Jello characteristics. Their are mounting tabs for both the Anycopter and Batbone/Tricopter designs from FliteTest. The included stl files are sized for the standard Anycopter/Batbone/Tricopter frames from FliteTest. You can customize the length of the battery tray and the location of the wire slots on the tray for your copters dimensions. 7/23/14: Added a version 3 of the main OpenSCAD file to allow the printing of 3 different camera trays. Two for the GoPro and a Mobius tray.The tray prints in three pieces, the Camera section and two identical battery tray sections. I glued the area on the battery tray just around the edges of the Camera tray slot with CA. Don't go to far back or you won't be able to get the forward wires into the tray. Note: Make sure the Camera tray slides all the way into the slot and the holes line up. Use Zip ties to hold the wire in the channels and the Camera tray in the slot. I have included a jig to help form the wire to the proper shape. The stl file has it orientated upside down. Just rotate 180 degrees before slicing. The wire I used was 1.6mm stainless that was relatively easy to work with but holds its shape well.
