Based on AxxAxx design, who did all the heavy lifting, with the modifications by Ahmet. This version adds holes for camera and LED. See http://www.thingiverse.com/thing:521078 for AxxAxx's original and https://www.youmagine.com/designs/z3-compact-case for Ahmet's filled backside version.Note: The cutout for the magnetic charger isn't perfectly centered (wasn't in the original either) and the camera and LED holes aren't sub millimeter accurate either but fully functional.(I pulled AxxAxx .STL into Fusion 360 to generate a modifiable model - thus the number of faces is very high if you download the .IGS file)When printed at "normal" quality in Cura on an Ultimaker 2 the case fits the Z3 Compact perfectly. When printed at "fast/low" quality less so.
