I found various examples of mounts for this switch but all were bulky, used a ton of filament, or didn't use the factory mounting holes. I had one of the original metal ears that came with the switch and used it to model these. The result is a very simple and easy to print model.
You will need to print 2 ears; one for each side. You will also need screws to attach them to the switch and screws for your rack.
The author marked this model as their own original creation.
