I recommend you take a look at my 3rd version of the cleaner.

Not applicable for A1 and A1 mini printers.

This is my version of a fairly precise cleaner.

To fix it, make sure that one of its halves is in the thread and then press the other half until it clicks (example in the gif). It is advisable to put 1 layer of paper towel under it. You can also use 2 layers, but then it is more difficult to snap the cleaner. The two protrusions on top are designed to facilitate fixation on the third screw opposite the door using narrow pliers.
