Since so many people have been asking in this thread recently, here’s a .zip containing all the parts in STL format:
v5_scuff_controller.zip (2.7 MB)
To be clear, I have no association with this project other than that I linked to it earlier in this thread. I didn’t realize the file linked on the online challenge site required a permission request to download, and I figured I’d save people the trouble of doing that plus installing F360 if they haven’t already.
The originator of this model is @Jasper_MCC, as indicated in his original post.
