Design 3d NPT fittings/pipe connections/pipes *STL and *STEP

I am looking for a person to design the following parts so that I can use them in Tinkercad and Fusion 360

-Pipe nipple (diam:4'',2'',1'',1/2'' /length:5,10,20,30,40,50 cm)
-Pipe Reducer (a) 4''-->2'', b) 3''-->2''/ c) 2''-->1'')
-T fitting (4'',3'',2'',1/2'')
-Elbow 90 degrees (4'',3'',2'',1/2'')
-Thread pipe connection male to male (4'',3'',2'',1/2'')
-Pipe Cap male (4'',3'',2'',1/2'')
-Pipe Cap female (4'',3'',2'',1/2'')
-Flange with inner thread (4'',3'',2'',1/2'')
-Union pipe fitting (4'',3'',2'',1/2'')
-Ball valve (1'',1/2'')
