I changed it a bit for better fit printed with my Original Prusa i3 mk2. Cleaned the STL a bit so further customisation (Blendfile!) should be easy. I made it a bit longer so that I could ease the printable but insane steep overhang.
So now you can print with layers >0.1mm (I used 0.15mm and I guess it will print fine with 0.2mm).
The original design served me well for many images as you can see here: https://goo.gl/photos/fN794VnbNKKwXzdv7
