Connector Designs for 3D-Printed Glasses: Part 1 of 2
For the Build Your Vision project, we are creating a template for a pair of 3D printed prescription eyeglasses. Olimpico will be providing glasses frames for our STEAM camp students to interact with this summer, as well as developing a lesson plan for Alta Vista High School students to learn how to conceptualize and design their own glasses, to create a prototype prescription eyeglass frame for low-income community members in Mountain View.

The main issue cropping up in the glasses design is how to connect the temple pieces to the glasses face. We would like to provide each summer camp student with a pair of frames -which amounts to over 250 pairs! Trying to create a hinge mechanism like regular glasses have is not feasible in this case. For such a large production volume, I have developed 3 simple designs I am going to test and eventually use as a prototype for the model. For the high school students, we will develop and work with a proper hinging mechanism, however at this point the goal is to create a simple connector designed for our younger students needs.
Each design has a temple piece, and a connection mechanism that will eventually be part of the glasses face. Since timing is an issue during printing, I am trying to keep the connecting parts for testing small, until I am ready to develop the full prototype. Here are the options I am sending to print. The next post in this series will have the printed results.
- Notch and slot -Face to Temple: The face of the glasses will have a notch on the back end that will embed into a hole in the temple piece.
2. Hook Together: This piece was accomplished by using the Boolean Difference command to take a chunk out of the face and temple pieces, so each slot will hook onto each other.
3. Notch and Slot -Temple to Face: The temple of the glasses will have a notch built up, that will slot into a hole in the face piece.
Now it’s time to get these prototypes printed, and experiment to see which option works the best, and is the most stable as a connector.
