It should work with any laser module of diameter of 12mm. They may look like the one in the third picture. This kind of lasers may engrave (but of course not cut) plywood as long as you get some high-watt ones and adjust them properly.

You should get more than one at a time because they get burnt easily if they keep working for too long.
it has a spot for a 40mm fan as well.
Please note that the face shown in the first picture (openscad one) is supposed to be facing the down side to the work plate when assembled. Also, you definitely want goggles on when working with lasers (even when t
