2.5" Tubing Coupler w/ 1.25" & 0.625" Side Connections

Summary This is a WIP for my brother's 240SX. I'm not entirely sure what is being coupled myself (lol) other than MAF fitting to aluminum intake tubing... and then between there's returns or vacuum or something. First print was undersized. When I get that right, we'll see about the rest. More to come...
