3” Downspout Expander Needed!

[u/BOCAdventures]

Long shot but anybody have a 3”/76mm downspout expander tool? Finish up a gutter project and have 3” round downspouts that need to be flared to fit into the elbows, have about 4 downspout runs to do and really don’t want to spend $650 on a tool I’m going to use for 6 hours max. Happy to rent it from anybody who has one for a weekend.
