As with Stvetecx's originals, the scales have the same dimensions as the original scales.
They fit toothpick, tweezer and needle. I've added the cutout for the blade locking mechanism and filled the scales for easier printing.
Watch out when dismounting the original scales - there's a little spring under the locking mechanism that likes jumping out and go AWOL.
All credits go to Stevetecx. My contribution is just a quick Tinkercad job.
Das Filament PETG
I recommend putting support under the blade lock sliding mechanism. You can probably get away without supports, but if you're using PETG or not enough part cooling the bridges may sag far enough to obstruct the mechanism.
