I mounted these on think CD jewel cases (2mm thick). I included a file for the base to print, but even on a .3mm layer thickness, it will take over 2 hours to print the base.
Please print the buildings themselves without supports, but for the roof please use supports from the build plate.
I would suggest printing at .25mm as the maximum layer thickness; ideally use .2mm but if you print at .3mm you may experience skipping in the print.
The chimney for the thatched roof for the cottage has a “stove pipe” as opposed to a masonry chimney. you will need to trim the mounting hole in the roof to ensure a good fit.
