I’ve recently been playing with those Neje laser modules, air-assist, and a manual Z-axis mount for them. It’s a bit more complex than those you’ve shown and I don’t know how much room you have on your Makita baseplate but maybe this will give you ideas…
It’s fairly compact and has ~75mm of Z-axis range…
and a sliding mount that provides a bit more adjustment. Here a Neje 40630 is mounted…
and an old style “20W” unit…
and mounted on a machine…
There is a motorized version that is essentially the same but provides a fully-implemented Z-axis…
