Thingiverse and Cults3d both have their fair share of crap.
I agree with you both, Burnie has built some fantastic models. If you like tanks, or other tracked vehicles, then check out
RC_3D_TANKS. I've got the files for a couple of his models, the M113 and the M551. I haven't BUILT them yet, but I've got the files. He models his stuff at 1/16 scale to use the Heng Long parts. I figure if nothing else I can use them as static loads once I get my trucks running, since all the Bruder stuff is 1/16.
This guy does good work too,
Russian self propelled combine Damned near everything appears to function on that model, even the cutter bar on the grain head moves.
I've been told that I
WILL get my garage door installed this week. Luckily my garage door faces east and I don't have a new garage full of snow - yet.
