Oofta, well, if it were me, Id take the other side off first, pull the bottom bracket out. and use the biggest easy out I can get my hands on in the center hole. Also, don’t use an electric impact in the future for install or removal.
You could drill 2 holes and use a 2 pin adjustable spanner . Maybe. Lots of pb blaster.
Drive side backward thread.
People down voted me for this last time. I don’t know why because I have successfully done it myself.
Weld the removal tool to the bottom bracket.
You can do it with a cheapest flux core MIG welder you can find and 1 hour of practice.
that bb cup looks still good enough to use your tool, given that it is a separate nut and not a one-piece wrench. use a crank screw and a washer and screw the bb nut in there with minimal wiggle room. turn the cup a 1/8 to 1/4 turn, make new wiggle room, repeat cycle until you can grab the cup with a pipewrench or something similar…
[edit]
this vid explains the method at about the 2:30 minute mark…

I use Pedro’s BB tool with the holder tool. It’s worked for me every time.
Vice grips turn to the right
Idiots stripped the teeth by using the tool counterwise to “unscrew” it not realizing it’s a LH thread.
I’m assuming turning the correct direction.. no offense, just have to rule out easy 1st..
If it’s like seized in there (i haven’t looked too in depth at everything, but I’m assuming some good suggestions already), mines going to be worse case scenario.. if can’t use BB tool, and again WORSE CASE SCENARIO, idk how nice of frame this is or what, but I’d have tried letting soak in a good penetrating oil over night, and maybe try a different BB tool, otherwise some type of special vise grips or channel locks… but if it’s seized, may have to heat frame around it…
Again, worse case scenario before everyone freaks on me..
I’ve had to do this with old vintage treks I’ve found in dumpsters etc, and pretty much only instance I’d recommend using “heat wrench.” If something old trying to restore
1) get the other side off
2) smack the spindle on this side with a hammer to punch the cartridge out the other side of the bike
3) thread a hacksaw blade through the BB shell and section the mangled cup into three pieces, being very careful not to cut into the BB shell itself
If the other cup is out, you should be able to knock the spindle out from this side, leaving only the cup. For a start, it would then be easier to get wd40 or whatever in the bb threads.
