Lazor Blade derivative

thingiverse

I printed about 30 of the original Lazor Blades by plasma2002 roughly four years ago. I'm now down to my last five and decided to remake them with some modifications. Specifically, I aimed to address a few issues: the hands that hold the razor blade would turn to charcoal and lose their grip when hit by the beam, while the arms were too thin to withstand multiple strikes in the same area before being cut by the unfocused beam. The main body also had a tendency to flare up underneath when the beam passed over it slowly on thick material, cooking the bottom of the project. With that in mind, I remade them with a hollow center, larger hands for a more secure and longer grip on the blade, and widened the arms. I increased the blade length slightly to accommodate cheaper Harbor Freight razor blades. These new Lazor Blades aren't as cool as the originals, but they suit my needs better. If I get creative again in four years, I'll make them look like an octopus with six arms. These were made from scraps of other projects, which is why you can see some staining on the wood. The 5mm underlayment used is cheap plywood from Home Depot. The blade-holding dimensions work well for my 40W laser at speed 25 and power 100, but your mileage may vary with a higher wattage beam or different kerf settings. I made these modifications because honeycomb boards have many thin metal pieces that can scatter the laser beam in various directions when hit, causing flare-up points that could damage the project material underneath. The Lazor Blades stand minimizes this issue. Be sure to use enough stands to keep cut pieces from falling and being hit by an unfocused beam, which could cause surface damage to the top face of the project piece. That's about it – I hope this explanation helps!
