Solder station remix

I remixed this excellent solder station to better fit my needs. Hopefully it also works for others.

-Increased the size of the hole for the flux pen to be more compatible with my own flux pen

-Lowered the solder guide so solder feeds from under the roll

-Made the guide sturdier

-Added an extension to the axle in order to hold soldering wick

Meshes were checked and fixed in simplify3d and windows 3dbuilder
