Fowler is purchasing 3 sets of supplies. 

First, there is the purchase of the syringe parts for a deposition tool.

Here is what those parts look like (until I get more info here, you can find the parts at fab@home:

Second, there is the set of parts for a motor. 

I decide to buy parts directly from Sherline that will move a saddle nut up and down.  We can then attack the piston of the syringe to the saddle nut (I think).  Why not?

Note that I already have a motor from the A-axis of the mill.  Assuming I don't come up with some clever reason why I need to rotate my plastic during 3D printing, I can use this motor for the syringe.  Note, all these parts together give me a means to move the piston up and down inside the syringe.  It is that brass saddle nut to the right of the picture which will move up and down and which I need to figure out how to attach to the piston.

Third, there is the plastic material to deposit.

I am going to experiment with two materials from day 1.  The first is from GE and called RTV 102 White/Blanc General Purpose Silicone Rubber Adhesive Sealant.

The second material is from plaster.com and is DryStone Casting Media.  I got a lot of this, so I will ask my wife and kids to play with it some in order to figure out consistency, etc over Spring Break.

So!  Fowler is on his way.  All he has to do is mill the metal parts to put all of this together on the Sherline!
