Some random lowpoly models from my project, most in md3 or blend format.
Add OBJ files!
Blender have obj export/import and mm3d have obj and md3.
I only use md3 (and md5) in my game, so I never keep the obj-files.
The left screenshot looks like from Cube 2: Sauerbraten. What's your project?
I'm using my own total conversion of Cube2-Sauerbraten, I call it SabiCube :
