Summary

I have a small car so I made a companion cube I can put on my antenna to make it easier to identify in parking lots
.
This is a remix of schlem's project which is a remix of poh's project.

My antenna is 7mm so you may need to change it to fit yours if you have a different size.
The first one of these I made flew off while I was driving so I put hot glue on the bottom of this one so it wouldn't but I could still remove it if I need to.
