On the list of places you should totally check out, thingiverse is the top. While a lot of their models are not in scale persay... that can be altered rather easily.
And once I made a laptop I found a microwave and mini fridge...
At my first barn, there was a viewing room that doubled as Ms. Atlas's office, and also a kinda break room with table, chairs, a microwave, and a mini fridge... It was also where all the bridles were hung... So we all basically hung out there and enjoyed our hot chocolate after a winter's riding lesson. Great times. But back to the model hobby, wouldn't it be great to also have the office part of that?
