Using a simple technique, I designed a very easy to make contraption that can secure the BB removal tool surprisingly well on the BB’s cup. There is a special tool for that but costs 30$. Then using IKEA’s standard metal table leg as a lever (5$) I removed the stubborn BB in seconds! You can read some instructions under the pictures bellow!
As you can see you only need two pieces of wood (round rod like a branch or something ). the smaller one needs a to fit into the hole of the BB removal tool. You can use a sharp knife for that and a drill for the hole where the rope will go in. The other bit needs two holes for the two ends of the rope (using the knife make an opening as seen in the pic so the one end of the rope can go in and out). This bit is your handle that you will twist until it tihgtens enough the rope around the bb tool.
Quite important: make a loop with the rope on the other side of the spindle.
Twist the handle until the BB tool is secure. Place the spanner vertically so the jaws wont interfere with the rope. After some twists the handle end will stop on the frame by itself.
This is how it looks like
Just take out the plastic cup and your lever is ready. You won’t believe how useful it will be!

Alternatively, you could get an M8 fine pitch (1mm) bolt, screw it with a nut and wide washer through a tool and then secure the tool with said nut.
The problem is that you cant find easily a bolt with the threading of the BB, atleast in my area
