Armor Case for Sony RX100 with 2cm nylon strap. Case has holes for flash, batteries and CF card.
I've sliced case for easy printing, put camera inside and glued 2 pieces together. So, it isn't possible to extract camera without breaking the armor case. But it is also more secure as there is no chance to accidentally open the case and drop camera.
I have plans to continue working on improvements and in next version will add hand grip, lenses cover and case locks (to be able to open case).
I've attached Sketchup files for customization.
