Victorinox A.7235 quattro screwdriver sheath for multitool or SAK EDC pendant

My multitool has a terrible Phillips screwdriver, so I decided to turn the Victorinox A.7235 Quattro into a pendant to carry with it. These are very easy to buy as replacement parts for different Swiss Cards and cost just a few euros. Without this sheath, the screwdriver is not suitable for carrying in a pocket, as it has sharp corners all around and will poke you at the worst possible moment.

The 3D-printed sheath is 29.5 × 24 × 4 mm and has a built-in 2.1 mm hole for a paracord that runs in the plane of the screwdriver, making the pendant as compact as possible. The hole features a slot to make it easier to reach in with a sharp object and push the paracord through.

The screwdriver is held in place with a clip that engages the 4 mm hole in its center. The nail cutout remains exposed, making it easy to extract when needed. It works much better than any friction- or magnet-based locking methods I tested and should be more reproducible across different machines.

Important note: the Victorinox screwdriver has a different edge finish on each side. The sheath is tuned to work with the Victorinox logo facing the clip. If you insert it the other way around, the clip will still engage, but extracting the screwdriver might require pliers.

Instructions:

• Print vertically, using a manual support enforcer only for the cutout used to extract the screwdriver. Make sure no support material is present inside the sheath, as it would be almost impossible to remove and is not really needed.

• I recommend high-quality PLA and 0.12 mm layer height for this print. PETG also works but makes the clip softer.

• Use Arachne instead of the Classic slicing algorithm to improve thin-wall quality.

• After printing, you may need to slide the screwdriver in and out a few dozen times before the clip starts to work smoothly. You might need to use pliers at this stage. The clip is firm, but a person with short nails should still be able to extract the screwdriver comfortably.

• If you’re not satisfied with how the clip works, try adjusting the scale of the print in the slicer until you achieve smooth action.

I attach both .step and FreeCAD files for easier remixing.
