Why I spent 2 months designing my own XTeink X4 case (and I almost gave up halfway through)
Following up on the interest from my previous posts, I wanted to share the real story of how this XTeink X4 case came to be.
Most people look at a case and see plastic. When I hold this, I don’t just see a product; I see the late nights, the discarded failures, and the stubbornness it took to make it work. Honestly, there were moments I stood at my desk, looking at a pile of warped, unusable plastic, ready to just give up and buy something off the shelf.
The struggle wasn't just about the "look". It was about three specific pain points that kept me up at night:
- The Light: I decided to embed it directly into the case, which forced me to learn how to solder for the first time. Let’s just say I have a few burnt fingers to prove it. Wiring the circuit and finding the right lens material to diffuse the light properly without harsh hotspots. Felt like a never-ending science experiment.
- The Buttons: My early prototypes were primitive just two separate, clunky pushers that felt loose. I wanted a solid, unified module that felt like a real controller. Designing the linkage to ensure they acted as a cohesive, satisfying click took more iterations than I care to admit, but finally getting it right was a huge breakthrough.
- The Freedom: I’m not always a right-handed reader. I needed a design that lets me flip the device 180° to switch hands. Balancing that grip tension while keeping it comfortable for either hand was like solving a puzzle that refused to click.
It’s not perfect. It’s got its quirks and it’s a bit "rough around the edges" compared to mass-produced gear. But knowing that every curve, every solder joint, and every button component came from my own frustration and eventual breakthrough... it feels intimate in a way store-bought things just can't match.
To my fellow makers: how many prototypes do you usually bury in the trash before you finally get it right?
I’d love to hear about the projects that almost broke you, but you kept pushing for anyway.
