A perfect mix of 3D printing and woodworking

A couple weeks ago I stumbled upon this woodworking guy's YouTube channel that is generally pretty silly, but he came up with a clever system to use 3D printing in a woodshop, the likes of which I've never seen before.Building a crosscut sled for your table saw is such a time-honored tradition that I've already built two of them. A crosscut sled lets you do things you'd normally only do on a miter saw because they're too dangerous or sketchy on a table saw. You also get way more accuracy making these cuts on your table saw versus most miter saws.But the problem with crosscut sleds is they deteriorate over time as you make various angled cuts or repeat cuts or throw in wide dado blades. As your sled's wood base and fences get increasingly cut up, depending on how often you use the sled, you might need to build a new one every few months.So I was intrigued when I saw this guy's setup where you build a sled with pre-determined slots that 3D prints fit perfectly into, so if you tear any…
