M.2 2280 SSD Storage Case Box — Sparekeep

A compact protective case for one M.2 2280 SSD. Only 11.1 mm thin, it fits any 2280 SSD without heatsink, NVMe or SATA, single or double-sided, and keeps the tiny M.2 screw with the drive. A taller version with a spine label is included. Part of Sparekeep, a series of storage cases for PC spare parts.

Two heights

• Compact, 94 × 34 × 11.1 mm: label on the lid. Thin enough for a drawer or a padded envelope.

• Standard, 94 × 34 × 17.1 mm: label on the lid plus a spine label for 9 mm tape, the same thickness as the other Sparekeep cases, so they line up when filed upright.

• Both hold the SSD exactly the same way.

Nothing touches the components

• The SSD rests only on the two zones the M.2 standard keeps free of components: just behind the gold contacts, and around the screw notch. It floats above a 2 mm gap, so parts on either side touch nothing.

• A tooth in the lid stops 0.15 mm above the board, next to the contacts. The lid never touches the chips, the label or the gold contacts.

• Sized for the largest 2280 SSD the standard allows (80.15 × 22.15 mm, up to 3.88 mm thick), with 0.3 to 0.4 mm of clearance: no forcing, no rattling.

• Two finger notches let you lift the SSD out by its edges.

• No foam, no hinge, no magnet: two printed parts, and the lid closes by friction.

The M.2 screw stays with the SSD

• Screw the SSD onto the printed boss, exactly like on a motherboard: the screw can't get lost, and the drive can't move.

• The screw cuts its own thread in the plastic the first time: tighten gently. Standard M2 screws up to M2 × 4 fit, and the lid leaves room for heads up to 5.5 mm wide and 2 mm high.

• The lid tooth still holds the SSD if the screw is lost.

Know what's inside

• Label area on the lid: 12 mm label tape or 12–15 mm thermal labels.

• On the standard case, a spine label area for 9 mm tape.

• No label maker? A strip of masking tape and a marker work just as well (see the photos).

• The cut corner marks the connector end, and the lid only fits one way.

How to use

Open the case with the end slots. Lay the SSD label up, gold contacts toward the cut corner, and drop it in. Screw it to the boss with its M.2 screw if you have one, then press the lid on.

Printing

• Already oriented: print both parts flat, no supports needed. PETG recommended.

• If your profile uses automatic supports ("Everywhere"), set supports to None or tick "Don't support bridges": the lid prints upside down, and the slicer would otherwise fill its label recess and engraving with supports. The recess floor prints as a short bridge, which PETG handles easily.

• With PrusaSlicer's default profiles (Prusa CORE One / CORE One+ HF0.4, 0.20mm BALANCED, Generic PETG): about 42 min and 20 g for the compact set, 51 min and 25 g for the standard set.

• Both versions test-printed in PETG on a Prusa Core One+, with a WD PC SN530 NVMe SSD and its M.2 screw.

Good to know

• PETG is not antistatic: touch something grounded before handling the SSD. For long-term storage, you can keep the drive in its antistatic bag inside the case.

• SSDs with a heatsink don't fit this case.

Specs

• Compact case: 94 × 34 × 11.1 mm. Standard case: 94 × 34 × 17.1 mm.

• Fits M.2 2280 SSDs: NVMe or SATA, M key or B+M key, single or double-sided (up to D5 class, 3.88 mm).
