Cherry MX PCB-mount stabilizer holes (2u, 2.25u, 2.75u, 6.25u)
Where do the stabilizer holes go for 2u, 2.25u and 6.25u keyboard keys? · Standard part · basis: KiCad SW_Cherry_MX_2.00u/2.25u/2.75u/6.25u/ISOEnter_PCB footprints (citing Cherry's MX catalogue)
Also called: stabilizer spacing, keyboard stabilizer holes, 6.25u stabilizer spacing, 2u stabilizer spacing, cherry stabilizer footprint, spacebar stabilizer distance, pcb mount stabilizer hole size, screw in stabilizer holes

Notes
- Keys 2u and wider (Shift, Enter, Backspace, numpad 0, spacebar) carry a wire stabilizer: two housings, one each side of the switch, joined by a wire so the key goes down level when pressed off-centre. PCB-mount (Cherry-style) stabilizers clip or screw into two holes per housing.
- Spacing is the same for 2u, 2.25u and 2.75u keys (housings 23.8 mm apart, ±11.9 mm from the switch) and 100 mm apart for a 6.25u spacebar (±50 mm), positions from the KiCad Cherry MX footprints. The small Ø3.05 hole is on the switch-pin side, the large Ø4.0 hole opposite (same y-up, keycap-side view as the switch footprint page).
- The files are drill jigs at true size: a ring round every hole (switch and both housings) joined by bars, to print and drill through or to import as the exact hole pattern.

Questions
How far apart are 6.25u spacebar stabilizers?
100 mm: each housing 50 mm from the switch centre.
Do 2u, 2.25u and 2.75u keys use the same stabilizer?
Yes: housings ±11.9 mm from the switch (23.8 mm apart) for all three.
What size are PCB stabilizer holes?
Two per housing: Ø3.05 at 7.00 mm towards the switch-pin side and Ø4.0 at 8.24 mm on the other side.
