Today’s focus is all about kerf. For those unfamiliar with the term, kerf is the sliver of material that is vaporised when cut with a laser or sawn away when cut with a saw. It’s usually the thickness of whatever is doing the cutting plus a smidge. By leveraging the kerf, it is possible to cut shapes that will then push-fit into others and remain there through friction. It’s particularly helpful when working with clear acrylic, which is tricky to glue without the glue showing up. That’s how I made these acrylic tealight holders using my xTool P2S laser and upcycled COVID screens for the main cube:

And some additional prototype designs for Christmas:
