I am transitioning management of these files to Gumroad: https://whatobiplays.gumroad.com/l/isoelq
This repository has the 3MF files for the devices featured in my silent button mod video: https://youtu.be/oYGS9zlUG38
I've already made the height adjustments to the specs in my video, so these are ready to print.
I recommend setting your slicer to print by object instead of by layer (which is the default). This will reduce stringing since the print head won't have to travel to a different ring between layers. These rings are so small you won't have to worry about the print head hitting another ring.
The handhelds folder has the files for each device. If there is a device you don't see here, feel free to open a pull request to add your 3MF file.
