+# Customizing the StenoToppers with AutoDesk Inventor
+
+It is very easy to adjust key dimensions of the StenoToppers if you have access to AutoDesk Inventor. All the dimensions (parameters) are linked to the top-level "parameters.xlsx" file, so simply follow these steps to change one:
+
+* Open the "parmeters.xlsx" file
+* Find the parameter you want to change (they are clearly marked / described)
+* Change it to your desired value (note that changing something too much may cause problems with the model, so modify only within reason)
+* Save the spreadsheet
+* Open the "stenotoppers.ipt" file in the "cherrymx" directory, using Inventor
+* Navigate to `Manage > Parameters Panel > Parameters` (looks like *f<sub>x</sub>*) 
+* With the parameters window open, click the "Update" button on the 2nd bottom row. The model should change to reflect your modification of the spreadsheet.
+* If everything looks normal, close the parameters window and the spreadsheet.
+* Export each iPart variant to STL format (see below)
+
+
+### Exporting to STL
+
+The StenoToppers model is what Inventor calls an "iPart", although you may have heard them called "Factory models" or "Factory parts". See [this tutorial][TFI-tutorial-iparts] for more information on iParts.
+
+Because the model is an iPart, some custom code was needed to export each variant to STL.
