Bucket foot

I needed something to put on my bucket vacuum's base to stop if from scratching stuff.
You can add a screw on rubber foot like I did with the 25mm version, or a 30mm felt pad on the 30mm version.

You can use the hole as a guide with a small drill bit, then screw the foot in from inside the bucket using that hole as a guide.

I added a drop of silicone on the foot hole, so the bucket would still hold water.
