Inspiron 15-7537 Laptop Sleeve

Somewhat of a first-world problem, but I'm looking for a snug laptop sleeve for the above - everything online seems to be about 20-30mm loose on the depth plane. The dell pages suggest the laptop's vital statistics are:

Width: 14.9” (379.4mm)
Height: 0.9” (22.2mm)
Depth: 10.0” (254.8mm)

Does anyone have a sleeve for this laptop they can recommend?
