Magnetic Effector for Lasers

It is a effector design primarily for Kossel800 by Maximscy, but should also work for any machine that uses effectors that match the dimensions of this one. (see picture 2 to check out) Technically this design could turn you 3DP in to a laser-engraver (a weak one tho).
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
