Repost of "The White House - Executive" by MakerBot ( https://www.thingiverse.com/thing:461235 ).

It slices at 100% scale in Creality Slicer and fits on my Ender 3 without a skirt.

I printed it at 50% scale at 0.2 layer height at 50mm/s and it came out great on an Ender 3 S1 with the default 0.4mm nozzle and 20% infill. It took about 3.5 hours to print at the 50% scale and 0.25 resolution." 

(Creality slicer says that at 100% scale, it will take 1 day 12 hours 13 minutes and 286 g of filament.)
