• The same part fits both the left and right side — the foot is symmetrical, so there is no separate left/right version to choose.
• There is no recess for the OEM rubber pad. These print solid and grip through a textured base surface instead of a rubber insert.
• Measure before ordering: each foot is 40 mm long × 19.8 mm wide × 4 mm thick. Compare against your original part to confirm fit.

• Material: PETG — chosen for its impact resistance and thermal stability over standard PLA
• Quantity: 2 feet (one pair — covers both sides of the keyboard)
• Dimensions: 40 mm × 19.8 mm × 4 mm each
• Fit: Snaps in on two locking pins, same as the original foot
• Brand: Unbranded aftermarket replacement

The MK670's tilt legs are thin parts retained by two small locking pins. Flipping the legs up and down over time fatigues those pins until one shears or the leg works its way loose, and the keyboard drops flat while you are typing. Logitech does not sell the foot as a service part, so the usual repair advice is to replace the entire keyboard over a part that weighs three grams.

Logitech Wave Keys MK670 Combo (920-012059, 920-012060) and the standalone Wave Keys ergonomic keyboard, keyboard model YR0096. This part is designed from the MK670 foot; if you have a different Logitech Wave model such as the K350, K550 or MK570, that keyboard uses a different foot and this one will not fit. Verify against your original before ordering.
