Just received the prints from JLCPCB, and honestly, it's a mixed bag. I know I was probably expecting too much given the price of the service, but if my cheap Bambu A1 Mini can do better… well, that's a yikes from me.

I had high hopes for the SLS 3201PA-F Nylon (black) and MJF PA12-HP Nylon (grey) prints, but these were definitely the most disappointing.

First impressions were promising: the parts feel tough and flexible, with a nice surface finish and a robust overall feel.

On the downside, both sets of nylon parts came out at different sizes. The front and back halves are undersized by varying amounts, so none of the screw holes line up. Comparing them to my home printer's FDM parts, they’re around 1mm smaller in both the X and Y dimensions.

The SLA resin parts (bottom-left white part in 9600 Resin and back-right off-white mystery resin), however, were mostly a win. I’m amazed you can get prints of this quality for as little as $0.66. The resin parts are tough, just flexible enough to allow the keyboard to actuate nicely, and have a good surface finish with fine text details coming through well.

That said, the walls on the resin prints aren’t perfectly square, which makes aligning the two case halves a challenge. It’s probably worth ordering another round of all the different resins to compare dimensional stability and find the right level of flexibility for the keycaps.

Since then, I’ve made some progress on the 3D model to better fit the screen and speakers. The next update will feature a more finalized version of the casing.

Excuse the poor quality images, I'm terrible at documenting stuff!
