Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:6031401.
This is a remix of my previous castle parts. They were really sized for capping duplo and the crenelations were too small when printed at lego scale. So these have been redesigned with lego scale in mind.
The doors are from my original model and are available here. https://www.thingiverse.com/thing:5363654
Pairs very well with my Magnetopult for hours of medieval mayhem. https://www.thingiverse.com/thing:5953638
For printing don't use supports. The only model that needs support is the castle corner pieces which should be supported only under the main overhang, not in the area where the bricks will connect. The brick connection side should be on the build plate.
