The third medical equipment had to be modeled as the “Stethoscope”. This is an instrument that is used by Doctors in determining and studying the heartbeats of a patient. A stethoscope can be used to listen to the sounds made by the heart, lungs, or intestines, as well as blood flow in arteries and veins. This was the reference image that was been allocated to me for modeling purposes.
To begin with, a stethoscope has various parts which include Ear piece, ear tube, Binaural spring, tubing, stem, and chest piece.
To begin with, I started modeling the earpiece also called an ear bud. I modeled it by taking a curve that depicts the piece of that earbud, followed by revolving it 360 degrees to get a circular shape.
After the earpiece, it was time for the ear tube. For modeling the ear tube, I took a Poly Tube object and added the tool “Bend” to it. What the tool bend does is, that it circularly deforms the object as per needed by the user. So for this reason I gave the tube a bit of bend and formed the ear tube.
Then coming to the Tubing, which was one of the trickiest parts of this process. I took a poly Torus for the start and deleted the unwanted part of it. After that just like the of ear tube, I took another tube and deformed it by giving it a bend. But specifically for this tube, I made the bend a bit more to get the spiral effect to it.
Now here comes the trickiest part, where we have to join the upper torus to the deformed tube. Firstly, as the torus was not in a shape that would join the tube, with the help of sculpt tool, that I used in the IV bag project, I pulled the faces and surfaces of that tube and made it so that it aligns perfectly with the end of the tube. Later on, I merged the vertices of the tube to this deformed surface which helped me in getting a combined model. But after doing that, I still got some jaggy edges to the combined geometry. Hence, I again used the sculpt tool to make it look like it! object.
And coming to the final modeling part i.e. The chest piece. To start with I took a circle cut in half and filled the hole init. Along with it, I gave it a lot of segments so that I can manually do the changes that are needed. I selected a few center faces of this filled part and with the help of smooth editing (when the points are selected press ‘B’), and pressed in down. Thanks to the smooth tool I can bend the faces systematically.
Later I grabbed the bottom face that is in a line and extruded it to I can get a tube-like thing on it, and carried the same technique for getting the desired chest piece shape. After this a grabbed an edge on the side and gave it proper extrusion which would resemble the Tube which connects to the Main tube of the stethoscope.
Coming to the final part: Rendering and Texturing.
For tube and ear bud: Arnold Standard material’s Rubber preset.
For the Chest piece and ear tube: I used the metallic preset of Arnold material.
