remember to add enough clearance so the key can fit and move properly in the key opening
Thought for 7 sec
Understood. The openings must follow the larger upper key bodies, with sufficient clearance for free movement—not just static fit. I’ll derive clearance from the STL geometry and account for PCB routing tolerance and key travel/wobble.
Execution is paused because no ACUs are currently available. The existing 59-opening pattern remains unchanged; the STL-derived complete pattern, irregular space-bar opening, and movement-clearance validation still need to be completed.

Manufacturing Notes
Scope
This project is the KYB1 companion faceplate PCB, a mechanical-only board. Its datum and orientation match the 124.0 × 90.0 mm main KYB1 keyboard PCB, centered at world origin with +Y toward the top edge.
Manufacturing package
Export this faceplate as its own Gerber and drill package and include both outputs alongside the main KYB1 manufacturing set. Do not merge this board into the main keyboard PCB fabrication data. Confirm with the fabricator that the 69 rounded rectangular NPTH features are interpreted as routed openings in the drill/rout output.
Supplied STEP validation and key opening geometry
- Validation source supplied in project chat:
BLKMGK_KYB1-keyboard.step(https://cdn.flux.ai/project/chat/attachments/BLKMGK_KYB1-keyboard-839d58ca-0365-4681-9c35-98c1dab13405.step). Header identifies a PrintNexus faceted-mesh STEP in millimetres. - The repeated key protrusion section was measured from the faceted STEP vertex geometry using local key-array axes and oriented envelopes rather than raw world-axis bounds (the assembly is slightly tilted in the STEP coordinate frame).
- Measured maximum-material protrusion envelope is approximately 5.10 × 4.34 mm in faceplate X/Y, with a rounded-oblong profile. The tessellated corner sequence indicates an effective corner radius of approximately R1.1 mm; this is a faceted approximation, not an analytic CAD radius.
- All 69 key profiles use the same repeated geometry. No meaningful key-to-key size class or outlier was found beyond STEP tessellation/coordinate precision (approximately ±0.01 mm at the reported envelope precision).
- The former provisional 5.5 × 4.5 mm R0.5 openings left only about 0.08 mm clearance per side on the measured 4.34 mm axis, so they were enlarged.
- Applied practical clearance: final 5.6 × 4.9 mm, giving approximately 0.25 mm per side on the measured 5.10 mm axis and 0.28 mm per side on the measured 4.34 mm axis.
- Final openings: 5.6 × 4.9 mm rounded rectangles, R0.5 mm, NPTH/HOLE. Each SW1–SW69 node now carries an explicit 5.6 × 4.9 mm holeSize plus a closed rounded-rectangle custom pad path; this supersedes the former ineffective size-only overrides and is intended for the NPTH drill/rout output. The smaller opening corner radius is intentionally non-restrictive relative to the key's more-rounded approximately R1.1 corners and is straightforward for routed fabrication.
- Count and datum: 69 openings, centered on the existing corrected SW1–SW69 coordinates; centers were preserved.
Final mechanical geometry
- External outline: continuous 124.0 × 90.0 mm rounded rectangle, centered at (0,0), with R4.0 mm at all four corners.
- All former connector/edge notches associated with J5, J6, and J7 are removed. The perimeter has no connector cut-ins.
- Four Ø3.7 mm NPTH mounting holes are preserved at (-57,-40), (57,-40), (-57,40), and (57,40) mm.
- Existing useful top-face identity/orientation marking and WORDFACE artwork are preserved.
D93–D95 LED-hole checkpoint
D93–D95 PWR/STATUS/PGM LED openings remain intentionally omitted pending explicit user approval. Do not add LED holes until their diameters and coordinates are approved. The existing informational front marking may remain, but it is not a routed opening.
Authoritative sources and conflict resolution

- Corrected center-coordinate sources:

faceplate-alignment-mismatch. - The original user-supplied
faceplate.svgremains rejected for fabrication because it does not match the current PCB perimeter, mounting pattern, pitch, or opening count. - Where the old corrected faceplate assets show J5/J6/J7 edge notches or 3.5 × 4.3 mm key openings, this manufacturing note and the current live faceplate layout supersede those details.
Release checkpoint
The previous STEP-unavailable blocker is resolved. Before ordering, confirm the fabricator's routed-slot tolerance and that 0.25 mm nominal minimum per-side clearance is acceptable for the selected faceplate thickness, finish buildup, and keyboard-to-faceplate registration stack. A physical first-article fit check remains recommended because the supplied STEP is a faceted mesh rather than an analytic tolerance-controlled source model.
