This pen is designed off of the .50 BMG cartridge.
I have created 2 versions of the pen tip, and case. The files starting with "SOLID" means that the majority of the part is 100% solid. The ones that are not named "SOLID" have minimal plastic in it.
The SOLID parts add a lot of mass to it, which makes it feel better.
The Pen Cap is held in place with friction.
What to print:
1x 50 BMG Pen Tip
1x 50 BMG Shell
1x Pen Cap
How to assemble:
Insert 50 BMG Pen Tip into the 50 BMG Shell.
Insert Bic Pen tip into 50 BMG Pen Tip.
