Where to get the Slic3r configuration files for the 3D PrinterWorks Creatorbot printers?
Looks like 3dprinterworks.net went down sometime after March 2018 and 3dprinterworks.com went down in January 2019. Luckily the Wayback Machine still has the machine's specs.

Here is the instructions for entering settings in Slic3r as found here in lieu of importing a profile. (Please note that I have not used Slic3r so the following is solely based on the link)

The key settings under General are 


Bed size*: X = 305 mm; Y = 305 mm; and Z = 457 mm
Print center**: X = 152.5 mm; Y = 152.5 mm
Extruders: 2
Heated Bed: Checked


Under Extruder (each extruder should have its own settings so be sure to set up both)


Nozzle diameter: 0.4 mm
Extruder 2 offset: 30.9 mm (good job, OP on finding the email stating this)
Everything from Retraction and on is up to what works best for you


There may be a set of setting for acceleration (there is in Ultimaker Cura) which is 3000 mm/s2 for most printers, I think. This is the max acceleration, not to be confused with acceleration settings when slicing the model.

The next set of settings, though outside of the Slic3r link, regards the filament. The diameter should be 1.75 mm and the nozzle temperature should be within the range of the filament (e.g. PLA should be set within 180-220 °C) and a heated bed set to 50-60 °C. These parameters are filament dependent and not printer dependent (other than diameter).

That should be the settings that a profile would set for you. Thankfully there's not too many.



*There is a wizard for this section that may make input easier, but here is the build volume. 
**This setting may require whole numbers and may, in fact, not be a necessary setting at all.
