Pudge Fountain Pen body for Kaweco Sport Nib Unit

The Pudge Pen is meant to contain a Kaweco Sport nib unit. It is called Pudge because it is a seriously pudgy pen, kind of like a Sharpie bold paint pen. Why make the pen so large, you ask? Because they are comfortable for people with arthritis or other conditions that make it hard to hold a narrow pen. Also, there's just something kind of fun about having a pudgy pen. 

The pen cap has a cool swirl, and this functions as a roll stop.  The one issue with the design is that it doesn't post. At least, this version doesn't, though I may make one sometime that does. 

WARNING: Don't force the nib unit into the body or the cap onto the body at first. Twist until you feel resistance, then untwist, then do it again. Keep doing it until it doesn't resist and the unit easily screws in.  Otherwise, it could get stuck partway or even break the pen body.

Remix details: I used thesaxmachine's model for the screw threads, etc. I did not like that when the pen's cap is on, there are screw threads on the end of the pen, so I eliminated those. I changed the cap to have a spiral because I like it that way :)
