@variablepulserate I paid $25 at ALDI for the Bondic repairer. It comes with a pistol-like over & under tool that has a 4 ml tube of liquid plastic filler below a UV LED thingie. There are comprehensive instructions, a second tube of goop & the whole lot is in a tin box.
Replacement goop is $10 each but various bulk packs reduce that unit price to $6 if you buy 15 of them. Personally, I’d try a different (cheaper) brand of filler.
Having said that, if the coffee maker hadn’t been fixable it would have been over $40 for a new one.
