This is the model of the Karazhan Tower from World of Warcraft Alpha.
This is not an easy print, there are some very small spikes, and lots of overhangs.
The original model has the full interior as well, which doesn't need to be printed as you can't see it unless you cut it in half.
So I manually removed all the interior, kept the doors, kept the observatory, and minimised printing time and filament cost to minimum.
I printed this with a very sticky filament and completely missed support removal, please disregard the bad picture !
It can be printed and with some PLA-Support or just proper interfaces and dry filament. You'll get better results than I showed :)
Feel free to scale down, this one is a beast, but not too much for small details.
Enjoy!
