I was looking on thingiverse for a tardis model and came across a really neat Siege Mode version. I wanted to print it but no side was flat and the geometry was too dense and messy to clean up.
So I decided to remodel a clean and poly-efficient version myself based off this paper printout version as my template: http://papermau.blogspot.com/2015/01/doctor-who-siege-mode-tardis-paper.html
100% scale: Minimum 0.4mm extrusion width/nozzle and 0.2mm layer height. Support only needed for the bottom 4 notches.
Smaller than 100%: Finer details will be lost unless printed at a finer extrusion width/nozzle size.
Larger than 100%: Larger extrusion width than 0.4mm possible, consider adding supports to side details and notches or chop model into individual sides.
