I've been working on a larger project. Which I hope to post on here in the coming weeks. I find that sometimes it best to break projects into smaller pieces. Little milestones make bigger projects flow a lot better. The enclosure for my new project requires a holder for OLED display. I've never modeled anything like this before. So I decided to do a small project out of modeling a holder for it. Here we are now. I present to you my holder for a 128 x 32 OLED display.
I used TinkerCAD to create this model. It's a fairly simple concept with a hidden feature. More about that in a minute. The model consists of two prints, the holder body and bezel. The OLED display I'm using is a 128 x 32 sized display. It uses a I2C connection which requires four pins. Here's where the hidden feature comes in. I wanted to keep the holder a modular as possible. In the sense that the display could be easily pulled out and reused if needed. In order to that I had to come up with a design that kept the OLED display as stock as possible.
On the back of the display I soldered a standard breadboard friendly header. This allows me to plug this directly into a breadboard if I wanted to experiment with it. This got me thinking. What if I could make some sort of socket that allowed me to plug the display in and remove it as needed? Then it hit me. I could use female headers like on a Arudino board. To keep it simple, I used premade female dupont wires. All you have to do is push the four dupont connectors from the back of the holder. I modeled the rectangular hole with a fairly tight tolerance. This forms a friction fit. Then you can install the display from the front. Slide the bezel into the front of the holder and you're done.
