ErgoPen

Combined boths pens.
Added the ability for the Ergopen to be able to accept BIC pen refills as in the nostalgia pen after resizing it to 115%.

Was really hard to edit as all i had to work with was the stl, had to make my own pen, then make a "mold" for the finger indentations. then use that mold to transfer it on the new pen.

Please print with a raft so it doesnt fall down. Also make sure travel moves do not cross outlines to avoid any inner retraction strings from making the pen refill not fit smoothly.

**UPDATE 5/22/2019
Added a new version, which moves the tip 6mm closer to the fingers for a closer writing experience. This version may be easier for those with smaller hands.
