How to model something using reference images?

I took reference images for earbuds that I am trying to 3d model and I don't know how to go about 3d modeling it. I try calibrating the images but they never line up how I want it to. How would you go about modeling this? I included the images and the file of what I have done so far. Thanks!

There is always distortion in photos. I take photos from the greatest possible distance and fill the frame (longest focal length).
Calibrate the part, not a scale next to it.

Once you're done with @wersy's suggestion, I would use T-Spline modeling for this.

How would you t spline model this? I just don’t see how with the organic shape of it. Thanks!

@champshire91 the model you attached to your initial post contains a T-Spline ?

I see. Thanks! I’m just not very familiar and comfortable with doing lofting and all of that yet I guess

If you want to model such curved geometry, and when working with sketches, lofting is an absolute must and for product designs such as this, surface modeling is required.

Or, you just use T-Spline modeling 😉

I went back and looked at @grgroupbangalore_seo other posts and believe this is generic AI slop! Iv'e reported it as such.

Oh yeah, I forget that forms are a form of t modeling 😅

Oh ok thank you!

Hi! I would create a symmetric oval profile with a center line. Revolve half of the profile 180 deg. Then use Scale command -> Non-Uniform option to stretch the body width-wise and length-wise.

Many thanks!
