I designed some custom scales for my Leatherman C33t inspired by Tom Sachs Leatherman drop a few months ago. Printed on a 3ntr A4v2 in ASA and HIPS (industrial machine at my work). 100% infill though that doesn't really matter since the parts so so thin there isn't any infill layers. The holes are printed small to be bored out with a drill bit to the proper size for a tight fit (edit, these should be printing at the proper size with thick wall and won't need to be reemed out on most printers).

Models are split into the Scale and the L (left) Scale with N AS A letter split in seperate bodies. If you have multi color capability, you can import each scale all at once (scale + N + AS + A) and the origins should line up automatically and place the lettering inside the scale to be colored. You could also print the scale without the lettering inside on a single extruder printer and fill it with paint for the same effect with a bit more work. There are two options for the right side scale, with and without the lanyard loop.
Please do not sell these or modified versions based on my model without my permission.

Update 1: Updated Scale_L to have the proper inset for the screws so they sit flush and can be tightened all the way down. Also added an alternative Scale_L with a loop for attaching 550 paracord (like the Tom Sach's Leatherman as well). The 550 paracord is just under 4mm and the hole is 4.25mm. I suggest cutting the paracord and putting some scotch tape around the end to prevent fraying when putting it through the loop. I used red shrink wrap to secure the lanyard and am very happy with how that looks. One end is shrink wrapped and one end has a end cap bead. As bead I used a 4mm brass threaded insert I had laying around because I liked how it looked. Eventually I plan on resin printing a more detailed custom knurled bead as well.

Update 2: Moved the lanyard loop to the other side of the tool to remove interference with the philips screw driver opening all the way. The lanyard loop is currently a little thinner and weaker then I'd like so next update will likely be a thicker reinforced version of the lanyard loop.

Print's now available from my Etsy store with optional lanyards:
