Ablenet Big Mac Inner Ring Replacement

This is a replacement inner ring for an AbleNet BigMack switch. In the pictures, you can see that I've removed the original inner ring, and replaced it with this 3D printed model for testing. It seems to work just as well as the original, and with the big switch top screwed on, you should never know there's a replacement part in there.

If you're looking for a replacement for the threaded part instead, you can find a model for that here: https://www.printables.com/model/344249
