Thanks MoRayCH for the original design. Holes were just too small for standoff (maybe because it's not original ZMR I've got ?). Here is version with a little bigger holes (6mm instead of 5mm) I've managed to print bumpers with Ninja semi-flex (100% fill) filament in order to absorb frontal shocks Second remix for bumpers, bigger (better protection), and with 5.8mm hole to fit standoff with ninja semi flex filament. You can purchase complet gimbal kit (print (ABS/Ninja Semi flex), servo motor, and Pushrods / music wire 1.2mm) directly from my eBay store: http://www.ebay.com/sch/yoannwyffels/m.html 05 june 2015 Added "Simplified Panels_attachw_ziptie.stl" file. Source panels are a little bit weak in case of crash. I've decided to create panels which were going to be hold with zip tie on standoff. Servo holders / And camera holder holes are also a little bit in the back. This STL files are in testing mode for now
