Oh, I also made up a 3D Printed focus knob with knurled edges, 32mm in diameter. I will post it up on Thingiverse once I get a chance to test it. It is in OpenScad, so parameters can be customized however you like. I chose 32mm because it should just stick out from my carriage for easy...

I bought some red acrylic and have received my Eagle safety goggles, so I will try a test to see if it will work well enough for a window (of course assuming safety goggles will be used as well.) And you and I were thinking alike about the camera. I grabbed a couple of cheap cameras and a 7"...

Thanks for the answers, Hakzaw! That was what I expected. I have designed my carriage to hold a 25mm fan or TEC against the heatsink in case I need it. Also, thanks for suggesting I could do an ezfocus knob with ABS. I will give it a try. I guess the worst is that it gets hot and falls off. I...

I happened upon a few examples of that laser safety acrylic after my last post. $200 per sq. ft. is way out of the price range of this project and not really worth it just to have a window. I am planning to change things up a bit and just have the whole thing enclosed. If I really, really want...

Hmm... since I am not sure where to find the OD rating for different plastics, or where to purchase any special purpose plastics, perhaps I need to leave the window idea out. Glasses will be worn when operating it, but there will be others around that may walk in unaware of the laser operating...

Blacklight is UV-B isn't it? But anyway, I get your point. Of course goggles will be used. But that doesn't mean anyone extra that happens across it will be wearing them. So, I am not really looking for something to replace the glasses, but instead to offer some level of protection. The lens...

I am building a laser engraver cutter using a 445nm 2.5W diode. I am building the whole thing into an aluminum briefcase about 5" deep. Cutting area will be 12x12 inches. The briefcase has locks (which I will be adding switches to for interlocks.) But I wanted to put a window in the top to keep...
