Great idea! I should probably make something like that as well, using a short bit of teflon tubing as the "detector" part, attached to a switch. I already have a switch connected that pauses the print and moves the hotend if the filament runs out. I can just wire the bulge switch in series, which will pause the print so I can sand down the bulge. Thanks!

I do this too, using one of the buffing pads for a Dremel. Quick and easy.
