Trying to Fix Things My Home With 3d Printing

I have an old clock in the shape of a vintage boat steering wheel hanging on my wall. A few years ago, when I removed the clock to replace the battery, two of its arms broke. At the time, I didn't have any glue, so I set the broken arms aside, thinking I would fix them later. Unfortunately, I forgot where I had put them. Consequently, we used the clock without fixing it. Just now, I remembered that I could create a 3D model of the clock's arms and have them 3D printed. I am excited to see how well they fit and work!

Supplies

3d printer or 3d printing service
Glue
scale or calliper

Step 1: Reference Photo

To begin, we can take a picture of the clock handle. It's recommended to use a white background to make it easier to see the shape of the object. I placed the handle flat on the table and took a photo from a bird's-eye view, using flash to minimize the shadows.

Step 2: Reference Length

When using Fusion 360 for redesign, we need to measure one dimension for scale. I measured it as 9cm, which is the length of the handle. We can use scale or calliper for this task

Step 3: 3d Modelling

We can start by importing the fist image we took for reference as canvas

After importing the image palace it in the work space , open the canvases folder and right click on the calibrate

Now with the mouse pointer click the top and bottom of the handle any enter the length we measured in (90mm)

Now the image is at correct scale now we can tarce shape of the handle. Start by creating a new sketch in the top of canvas and open the fit point spline tool

We only need trace one half of the handle

Draw a line between starting and ending of the tarce using the line tool and click the fish sketch

Now hide the canvas

Using the revolve tool we can create a shape from it . select the inner part of the sketch as profile and the line as axis and click ok . now our shape is created

Now we nee to make it hollow for saving material when 3d printing . we need to use shell tool for this job . open the shell tool and crate a 1mm shell of this body and click ok

Next we make a 15mm hole the back side of the model . we will use hole tool for this

To export this model as .stl . right click and save as mesh

Step 4: 3d Printing

We can now 3D print a replacement handle. I used an online 3D printing service for this. After a few days of waiting, I received my 3D print. Unfortunately, I could only find black material for the print, as I couldn't find a wood colour, but it still blends in well.
