To all people using blue lasers. Do not use cheap green googles. Add some money and buy those! In fact they are not OD4 but rather OD3 but still enough to protect your eyes for <5W lasers. Certified googles are 10-20 times more expensive so after local certification using some laboratory instruments I have the best googles for the price ever :D

There were missing couple of nuts and two frame connectors. Also it is not so trivial to set up machine to have everything parallel and smooth it needs very precise adjustment. But after adding components and fine tuning it works like a charm.
