This is a project under the Fusion 360 Challenges provided by Knowledge Point. I thought of making this instructable to help all those who are struggling with the challenges. Please refer to the pdf and STL files attached to this Instructables for the dimensions. You can also view this screencast for a quick preview of what we'll be doing in the following steps.

Step 1: Creating the Base Body

Create the sketch
Extrude the body
Cut the given dimensions from both the top and bottom sides

Step 2: Adding the Holes

Sketch the circle on the two front ends
Extrude the profile to create a hole
Use "Thread" command to create the thread

Step 3: Adding Fillets and Chamfers

Add fillets to all the sharp edges (use Radius= 1mm, unless otherwise mentioned)
Add the chamfers to edges of the front end

Step 4: Creating the Rendering

Add a decal of your choice (Use Fusion 360 logo if you are making this for the challenge)
Save the file to start the rendering

Good luck to those who are taking part in the challenges. When you're done, please share you rendering here too using the "I Made It" button.

Step 5: 3D Print It (optional)

Having created the model, it's quite obvious if you want to print it. I don't have a printer. Thanks to the My Mini Factory community for printing it for me. Here are the technical details:
