**Introduction**

Hey guys! We're Evan and Katelyn, and today we're gonna show you how to make your own custom hose adapters. Already know how to 3D model? Awesome! Don't know anything about 3D modeling? We made templates for you guys to make it really easy. We're going to walk you through a couple ways to do this, but they both start with measuring.

**Measuring and Creating Templates**

We need dust collection for our table saw, but the connection doesn't fit with our dust collector, or shopvac. We use digital calipers to measure. Even inexpensive ones are more accurate than any ruler you can find. Hose connections are tapered, so you have to measure in a couple places. Eh, just screen-cap this for instructions. So, we're going to use these measurements we took earlier to modify our templates. We linked to all of them below, and there's a bunch of different types that you can choose from.

We need a straight reducer for the table saw, so we'll use our straight reducer template. We use a program called Onshape. It's free and browser-based, so you can use a cheap computer and access it from anywhere. You'll need to create an account, and then open the template link that you want to use. In the upper-left, make a copy of the document, so you can start editing it. Click the front side of the cube, to view it straight on, then double-click 'sketch' to see all the dimensions.

The variables on the left define these dimensions. If you click on any of the dimensions you'll see what variable defines them. Select the variables you want to change, and type in the measurements we made earlier. When you change one number, it will update the whole model. You can turn the 'section' view on and see a cross-section and make sure nothing looks crazy. And that's it! A couple of number changes, and you're done with your model.

**Modifying Pre-Made Templates**

If the templates were enough, go ahead and skip forward to This time. We'll cover how to make this model from scratch if you want to get into 3D modeling without using our templates. In 3D modeling, you almost always start with sketches. These are 2D until you either extrude or rotate them into something 3D. This time, we'll start by creating a new document.

Next, create a new sketch and define a plane for it to be on. I usually work on the front plane. We'll use the line tool, but turn it into a construction line. To define the shape of the 3D model, we'll sketch just the slice of the adapter shape with the line tool. This will be rotated into a solid model around the center line that we just made.

It doesn't have to be exact, because we'll define the dimensions next. Before we do, let's flashback to this guy to remind ourselves that this surface is defined by two offset diameters and a wall thickness. Now we'll use the dimension tool to define the sketch. For diameters, click what you want to define, click the center line, and click on the opposite side of that center line. The first dimension you add will scale the rest of the sketch to that dimension.

To define the wall thickness, just click between these two points. To add a diameter part way along the line, we'll have to add a point. Don't click on the box that pops up halfway along this line because that will set this point as the midpoint. Add the offset distance. Define the internal taper. And finally, define the wall thickness.

**Creating from Scratch**

Now that you've watched this video you can make ALL THE ADAPTERS!!! I'm Edward Adapterhands Hehe! Edward Adapterhands Hope you enjoyed this video! If you have any questions, just let us know in the comments. And if there's a frequently requested size or shape, we'll make a new template and add it to the links below.

We wanted to thank you guys, and Bob from I Like to Make Stuff, for the encouragement to share these designs in this how-to. And as always, please like, subscribe, and share this video. It really means a lot to us Thank you!
