It didn't quite fit on the Dirtdevils' holder. I removed 0.3 mm on each side and 0.2 mm of the top. I shortened it to 42 mm to fit the brush mount floor vacuum thing :)

1. Remove the broken holder with a plier
2. Remove the remains with a coarse file
3. Double-sided tape and zip-ties
4. Use a heat gun to soften the plastic of the holder on the vacuum itself
5. Insert and let cool
6. ???
7. Profit
