Finished designing the enclosure for the macropad in Fusion 360. To make sure everything fit correctly, I exported the PCB directly from KiCad and imported it into the CAD assembly as a reference. This made it much easier to design around the actual hardware instead of guessing dimensions, as well as aligning the gap on the bottom for the underglow effect.
‎
I found models for the switches, rotary encoder, OLED display, and Seeed Studio XIAO on GrabCAD, which ended up saving a lot of time. Having the real component geometry available meant I could check clearances, mounting positions, and connector access.
‎
I can finally see the macropad come together! The electronics, PCB, and enclosure all exist together in one assembly, now I just have to write the firmware which I am leaning towards using QMK due to its customization.

Any feedback is appreciated!
