OBJ and PNG files to MDL (SFM)

Hello, I have extracted a gear from ROBLOX (Sorry for playing that) and it came with MTL, OBJ, and PNG files in the folder I set it to. I would like these files to go into an MDL file and QD files to go into Source Filmmaker. Heres a link to download a zip file with my extracted model: http://download1346.mediafire.com/h3bkiigdfzgg/vu0aw691pe84wac/Glider.zip

I need this for a project I’m working on with SFM.
