I really don’t use my K40 too much these days since I moved and am now near a makerspace with several more powerful and bigger lasers. Still, these days I am mostly stuck in my house and decided to dust mine off to assist in making facemasks to help a little during this pandemic. I have posted a video on youtube about it. That video won’t really be any interest to people here who have K40’s and know what they can do but below the video, I have links to laserdraw files for small, medium and large ‘fu’ facemasks. (google it) I also have the image that I imported in case you are using other software. I think that the large is meant to go over another mask since it is really huge.
