2021-05-03 (M) Wearable Macro Keyboard BackOfTheHand BotH IR Parts

I didn't have a clear idea in my head about how a dual-channel IR proximity sensor would look. When I started modeling, I couldn't land on a satisfying design. I kept going forward, hoping that I could shape something utilitarian and improve it with experimentation.

I added two pairs of holes between knuckles on the platform to have a stable mount for my infrared components. Next, I started a new model with matching holes and nut sockets. I created a 5mm LED model based on measurements and placed a pair of them to get an idea of how they should sit. I don't think they'll need to point further apart than sixty degrees, so I based the rest of the model on that premise.

The LEDs will mount in tubes where the replica model provides a perfectly shaped cavity. At the insertion end of the cylinder, I added grooves so the component should insert effortlessly, and at the far end, I put pinholes to direct a small cone of IR light.
