Start from this working example and replace any number with what you measured: Design a PCA9685 case, 64×27×16 mm cavity, 50×8 mm servo header slot, terminal and I2C openings, four M2.5 standoffs, 1.6 mm walls.
The Adafruit servo FeatherWing is a smaller 8-channel board. In SpeakCAD you open the ready-made model for free, change it to your measurements, then download a file sized for the part you actually own.
No. SpeakCAD runs entirely in the browser: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL or 3MF.
