This set of examples shows you how to create parameterized parts for Simscape Multibody and example MATLAB scripts for defining general extrusions. The parts have been used in a wide range of examples to show how these blocks enable you to rapidly model mechanisms. Within the library are a set of gear assemblies. The parameterized gear assemblies group the required blocks together and parameterize them so that frames are always positioned and oriented correctly.

Thanks Daniel. I considered adding the number of points as an optional parameter for Extr_Data_Ring. I decided to keep the list of parameters as short as possible, and hopefully the code is clear enough for people to extend it. Now that I have seen that this is necessary for some use cases, I'll consider adding it for all Extr_Data_* scripts that include arcs. Thanks for the feedback.
Steve, I mostly use the Contact Forces Library, but I noticed that the ring extrusion script is used here. Anyway, the visualization of the ring extrusion is clocked every degree which is probably okay in many cases, but I found the need to have the visualization of rings have more refinement. I've gone in and modified the Extr_Data_Ring script to divide the arc into 1000 divisions so it works for me, but I thought I'd throw it out there as a suggestion to refine the angular spacing of rings. (BTW, I've also noticed that visualizations of solid bodies using the Simscape Multibody "Solid" block are similarly coarse.)
I'm a bit new to Simulink, how do I get your excellent libraries to get into the standard simulink Library browser?
