Use these basic guidelines to help you design your own! ## Measure with Flex Tape Use a flexible measuring tape to measure the length of the headband. ![3d_printing_flextape-measure.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/792/medium640/3d_printing_flextape-measure.jpg?1652807535) ## Measure with Calipers Use calipers to measure the length, width and depth of the features on the headphones. Save your measures to a document to reference in your CAD software. ![3d_printing_calipers-measure.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/791/medium640/3d_printing_calipers-measure.jpg?1652807523) ## Import Canvas  Reference images can be used to trace the shape of the headphones. In Fusion 360, use the **Canvas** feature to import images such as JPG and PNG into your project. Use the calibrate canvas editing option to apply dimensions and adjust the placement of the image onto your workspace. ![3d_printing_cad-canvas.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/795/medium640/3d_printing_cad-canvas.jpg?1652808696) ## Draw Sketch Profiles Create a sketch and use the spline or line tool to create profiles by tracing the shape of the headphones. Apply sketch dimensions to create the desired length and width. ![3d_printing_cad-sketch.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/796/medium640/3d_printing_cad-sketch.jpg?1652808818) ## Extrude Forms In Fusion 360, create a form by select the create form feature. In the forms workspace, use the extrude feature and select the sketch profile. Enter a desired dimension in the distance field and click OK to accept. ![3d_printing_cad-forms-extrude.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/799/medium640/3d_printing_cad-forms-extrude.jpg?1652809009) ## Fill Hole, Mirror and Duplicate Double click the outer edge of the form and right-click to invoke the contextual menu. Select Fill Hole, test the different mode types for a desirable look and click OK. In the forms workspace under modify, use the Mirror Duplicate feature. Select the form and use a corresponding plane to mirror the form. Confirm weld option is enabled and click OK. ![3d_printing_cad-forms-fillhole.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/800/medium640/3d_printing_cad-forms-fillhole.jpg?1652809183) ![3d_printing_cad-forms-mirror-dup.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/801/medium640/3d_printing_cad-forms-mirror-dup.jpg?1652809216) ## Extrude and Combine The new solid form can be used to "subtract" from a solid body. Create an offset outline of your shape to create a new solid body. Extrude the offset profile and use a desired distance for the wall thickness. Use the combine feature to subtract the form from the solid body. ![3d_printing_cad-solid-extrude.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/802/medium640/3d_printing_cad-solid-extrude.jpg?1652809541) ![3d_printing_cad-combine.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/804/medium640/3d_printing_cad-combine.jpg?1652809674) ## Cuts and Openings Create new sketch profiles for making cuts and openings for various features in the headphones. Here a large opening accommodates for the headband hinge, and control buttons. ![3d_printing_cad-cuts.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/805/medium640/3d_printing_cad-cuts.jpg?1652809796) ## LEGO compatible Plate Create a new sketch and use the circle tool. Use sketch dimensions to enter a diameter and position the circle. Use rectangular pattern and select the circle. Use the following parameters to create features that are lego compatible. Click Finish Sketch when ready. - Circle Diameter: 4.9mm - 5mm - Spacing: 8mm ![3d_printing_cad-sketch-lego.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/806/medium640/3d_printing_cad-sketch-lego.jpg?1652810007) ## Extrude Circles Use the extrude feature and select the desired profiles to create the circles. Enter 1.8mm - 2mm in the Distance field. If needed, use the mirror feature to duplicate the extrusion using a corresponding plane. ![3d_printing_cad-lego-textrude.jpg](https://cdn-learn.adafruit.com/assets/assets/000/111/809/medium640/3d_printing_cad-lego-textrude.jpg?1652810943) ## Related Guides - [MONSTER M4SK Toon Hat](https://learn.adafruit.com/monster-mask-augmented-eyes-toon-hat.md) - [Portable Apple Watch Charger](https://learn.adafruit.com/portable-apple-watch-charger.md) - [Bluefruit Controlled Macetech RGB LED Shades](https://learn.adafruit.com/ledshades.md) - [Party Parrot Zoetrope](https://learn.adafruit.com/party-parrot-zoetrope.md) - ['Sup Brows](https://learn.adafruit.com/heybrows.md) - [How to Make Animated Graphics for Hologram Displays](https://learn.adafruit.com/how-to-make-animated-graphics-for-hologram-displays.md) - [Reebok CheckLight Teardown](https://learn.adafruit.com/reebok-checklight-teardown.md) - [TVA Pruning Baton from Loki](https://learn.adafruit.com/tva-pruning-baton-from-loki.md) - [Apple IIe Fruit Jam Enclosure](https://learn.adafruit.com/apple-iie-fruit-jam-enclosure.md) - [Adabot Toy Robot Friend](https://learn.adafruit.com/adabot-rp2040.md) - [Princess Peach LED Crown](https://learn.adafruit.com/bowsette.md) - [3D Printed Electronic Sunglasses](https://learn.adafruit.com/3d-printed-electronic-sunglasses.md) - [Prop-Maker Keyblade](https://learn.adafruit.com/propmaker-keyblade.md) - [3D Printed Google Glass Adapter](https://learn.adafruit.com/3d-printed-google-glass-adapter.md) - [Rainbow Chakra LED Hoodie](https://learn.adafruit.com/rainbow-chakra-led-hoodie.md)
