Kerfs are slits cut into wood. The right application of kerfs allows the wood to bend. I’m beyond excited about the possibilities combining laser cut kerfs and thin plywood. I found a box calculator website where you plug in dimensions and it outputs SVG files. I entered a 3” diameter and 6” height and downloaded files that easily went into my laser cutter software. I cut the box from thin plywood and glued it together.

The dimensions I entered were not the finished dimensions. It was 6” tall, but had a diameter over 3.5”, which turned out to be an awkward size, too big for pens or a dice cup, but OK for paintbrushes. I finished the wood with Howard’s Feed-N-Wax. I’m not a fan of butt end joints, which is what the seam on this cup is, where the edges of the wood come together without interlocking, but this was a very informative first kerf project.
