Skin is a script to smooth the surface skin of an object by replacing the perimeter surface with a surface printed at half the carve
height. This gives the impression that the object was carved at a much thinner height giving a high-quality finish, but still prints
in a relatively short time. The latest process has some similarities with a description at:

Operation
The default 'Activate Skin' checkbox is off. When it is on, the functions described below will work, when it is off, nothing will be done.
Settings
Division
Horizontal Infill Divisions
Default: 2
Defines the number of times the skinned infill is divided horizontally.
Horizontal Perimeter Divisions
Default: 1
Defines the number of times the skinned perimeters are divided horizontally.
Vertical Divisions
Default: 2
Defines the number of times the skinned infill and perimeters are divided vertically.
Hop When Extruding Infill
Default is off.
When selected, the extruder will hop before and after extruding the lower infill in order to avoid the regular thickness threads.
Layers From
Default: 1
Defines which layer of the print the skinning process starts from. It is not wise to set this to zero, skinning the bottom layer is likely to cause the bottom perimeter not to adhere well to the print surface.
Tips
Due to the very small Z-axis moves skinning can generate as it prints the perimeter, it can cause the Z-axis speed to be limited by the Limit plug-in, if you have it enabled. This can cause some printers to pause excessively during each layer change. To overcome this, ensure that the Z-axis max speed in the Limit tool is set to an appropriate value for your printer, e.g. 10mm/s
Since Skin prints two half-height perimeter layers for each layer, printing the perimeter last causes the print head to travel down from the current print height. Depending on the shape of your extruder nozzle, you may get higher quality prints if you print the perimeters first, so the print head always travels up. This is set via the Thread Sequence Choice setting in the Fill tool.
Examples
The following examples skin the file Screw Holder Bottom.stl. The examples are run in a terminal in the folder which contains Screw Holder Bottom.stl and skin.py.
> python skin.py
This brings up the skin dialog.
> python skin.py Screw Holder Bottom.stl
The skin tool is parsing the file:
Screw Holder Bottom.stl
..
The skin tool has created the file:
.. Screw Holder Bottom_skin.gcode
