The part prints best if printed upright, and with supports under the overhang.

Step 1: Open SolidWorks 2020, and select a new part. Don't forget to save your file frequently as you go. In the bottom-right corner of your Solidworks window, change the units to MMGS (milimeter, gram, second). Select the Right Plane in the design tree (the left column on your screen) to begin your sketch. Click on the Sketch tab above and click Sketch.

Step 2: Make a horizontal line starting from the origin. Then use the smart dimension tool to make it 40cm long. Click the green checkmark in the left column if everything looks good like the screenshot.

Step 3: Select the Front Plane in the design tree (the left column on your screen) to begin your new sketch. Click on the Sketch tab above and click Sketch.

Step 4: Select the ‘Circle’ option to draw a circle starting at the origin. Using the ‘smart dimension’ tool make the radius of the circle the same as the screenshot below. Click the green checkmark in the left column if everything looks good like the screenshot.

Step 5: Click on the Features tab and select the ‘Sweep Boss/Base’ option. Under ‘Profile and Path’ select ‘sketch profile’ and for the end circle (blue color) select the sketch of the circle (sketch2). For the line (pink color) select the straight line sketch (sketch 1). In addition, add the ‘thin feature’. Select one direction and make the thickness of it be 0.29 cm as shown in the screenshot. Click the green checkmark in the left column if everything looks good like the screenshot.

Step 6: Select the Right Plane in the design tree (the left column on your screen) to begin your new sketch.

Step 7: Start drawing circles with the ‘circle’ option. Little advice, make sure the center of your circles are aligned with the origin (you will see blue dotted lines). Create 6 circles in the same sketch.

Step 8: Using the ‘Smart Dimension’ option make the diameters of the circles the same as shown in the screenshot below. In addition, make the distances starting from the origin point to each center of a circle identical as the screenshot. Click the green checkmark in the left column if everything looks good like the picture below.

Step 9: Click on the Features tab and select the ‘Extruded Cut’ option. Select ‘Up to next’ under direction1’. If the grey arrow is pointing the opposite side, you can always switch direction by clicking the icon next to the ‘Up to next’. Click the green checkmark in the left column if everything looks good like the screenshot.

Step 10: Select the Right Plane in the design tree (the left column on your screen) to start your new sketch. Click on the Sketch tab above and click Sketch. We will be using the ‘circle’ option.

Step 11: Draw a circle making sure the center of your circles are aligned with the origin (you will see blue dotted lines). See image below.
[[Image:Quena2_11.png|500px]]
Step 12: Using the ‘smart dimension’ option, make the distance starting from the origin point to the center of the circle identical as the screenshot. Also, make the diameter of the circle the same as shown below. Click the green checkmark in the left column if everything looks good.
[[Image:Quena2_12.png|500px]]
Step 12: Click on the Features tab and select the ‘Extruded Cut’ option. Select ‘Up to next’ under direction1’. If the grey arrow is pointing the opposite side, you can always switch direction by clicking the icon next to the ‘Up to next’. Click the green checkmark in the left column if everything looks good like the screenshot.

Step 14: Select the Front Plane in the design tree (the left column on your screen) to start your new sketch. Click on the Sketch tab above and click Sketch.

Step 14: Make a vertical centerline using the ‘centerline’ option. This can be found by clicking on the arrow next to the line icon. Then use the ‘line’ option to draw the same line as the screenshot (outer circle). Click the green checkmark in the left column if everything looks good like the screenshot.

Step 16: Having the last Sketch selected, go under ‘Features’ and select ‘Reference Geometry’. Once you click on the little triangle to see sub-options, and select ‘plane’. You just created a plane!

Step 17: At this point, we need to make the plane fully defined. First, under ‘first reference’ select the vertical line you just created in the last step. Second, under ‘second reference’ select the area between the 2 circles (See screenshot - purple area). Now, right under the coincident option, you will see an angle symbol. In that box type either “26 deg” or “154 deg”. This will depend on which side the plane is leaning. Ideally, we want to have a small angle close to the top of the quena which is where the 6 holes are at! Click the green checkmark in the left column if everything looks good like the screenshot.

Step 18: On that plane you just created select ‘normal to’ and click on the Sketch tab above and click Sketch to create a new one. On the new sketch, select the ‘Ellipse’ option to draw the same shape as the screenshot. Make sure the oval has the same dimension given in the screenshot.

Step 19: Click on the Features tab and select the ‘Extruded Cut’ option. Select ‘All Through’ under direction1’. If the grey arrow is pointing the opposite side, you can always switch direction by clicking the icon next to the ‘Up to next’. Click the green checkmark in the left column if everything looks good like the screenshot.
