Mower Blade Balancer

This is a remix of thing:2307698. I redesigned it completely but wanted to give credit to the original design. The OD of the center hub is 17mm and if you request a different diameter I will provide. This is the first thing I've ever posted and im not on here very frequently so I apologize if it takes a while to respond.

Center Hub ODs generated:

17mm

I use this for my blades on my John Deere D125
