Castles optimized for DLP

Repaired the file to merge all of the intersecting geometries and make it water tight

Resized to be 20mm long on the long end, else too big for earrings. (still a bit big but hey)

Extruded the base to be thicker, and included the door inside of the slab to keep it from falling off.

There's a hollowed out model, but the drainage holes are too small so its a pain to get the uncured resin out.

The trees worked for me using a clear resin, but not for an eng tough resin (they did not fully connect, tips were too small).

Basically -- you probably want to hollow and add supports to fit your needs based on the flat STL model.
