This is Version 2.0. 

3 parts and a BIC pen. Then you can write and throw it across the room! haha I dont know how to add the cap with a brim to make it one print. sorry about that.

Assembly. 

When putting together, the patterns must be perpendicular to one another to line up the threads properly.  It can only line up one way because of the grip.

Like so.

Once together you can take a BIC pen cartridge and put it in place and thread to cap on so it can stay together. haha hopefully. JK i tested it somewhat.
