What size heat shrink wrap to use on a VESC?

I ripped opened the VESC from Enertion to cut off the long sharp pins and added on some hot glue. It’s currently just wrapped with electrical tape for testing.

What size of shrink wrap do I need to get for the VESC? my local electronic store only carried up to 1" so I have to look online.

Try 4" long by 2" wide


It should be 68mm width.
