MarcMartin3dnd over in Thingiverse published this excellent model, based on the sample map in the 5e Dungeon Master's Guide.
This is a version of this model optimized for the Prusa XL, specifically:
- It's made of two huge parts (that barely fit on the build plate) instead of 6, for convenience.
- It uses two colors.
The main downsides, compared to printing 6 individual parts:
- The top part needs a lot of on-build-plate supports, but I think it's worth it for the convenience. After some trial-and-error, I recommend just going for standard/snug - NOT organic or tree.
- The top and bottom parts don't fit each other perfectly, some manipulation would be needed such as sanding the connectors.
Printing instructions:
- The bottom part doesn't need supports.
- The top parts need supports on build plate + on the existing paint-on supports, mostly on some parts of the railing and on the pin holding the wheel.
- Some of the accessories are very small and delicate, a brim is highly recommended for these.
