Dimmer Switch Cap

We've lost a cap for our dimmer switches downstairs, so I 3d modeled a replacement in blender. I don't own calipers, so I just used a ruler and it worked out pretty well.

I printed two versions of this, one missing some walls because they were too thin for cura to detect. It still worked, but it would rock back and forth in the holder and would presumably fall out after a while, so I printed a newer one after tweaking the model.
