I liked all the other filament cutters out there, but they were all designed for the larger snap-off blades and not the mini 5mm ones. The advantages of using the smaller blades is cost - you can usually find the smaller utility knives at dollar stores and other bargain stores.
I remixed the Filament Cutter 60° by KK (itself a remix of Filament Cutter 45° by Pomi) to accept the smaller 5mm blades, as well as made some other small improvements.
Improvements & Features
Accepts the smaller 5mm wide utility knife blades.
Added a window on the side to aid in assembly so you can see if the blade is lined up with the slot.
Added a minor bevel to the blade slot so blade motion is smoother.
Added curves to the side to make holding the filament cutter easier.
Material (copied from original model)
One segment from snap-off blade 5mm width
2 pieces of screw M3 x 25 mm
2 pieces of ball pen spring (probably 20 mm length, 4 mm diameter, M3 screw must fit inside)
Assembly Instructions (copied from original model)
Print both parts, should not need supports, 0.20mm layer height is fine.
Take one piece of 5mm snap-off blade and put it into upper part. Use some pliers to avoid injury. There is a small mark near blade pocket which shows you where the tip of the blade should be. Additionally, you can use super glue to fix it in position.
Put both screws into the holes.
Put ball pen springs into the holes.
Place the upper part on the main body and press it fully.
Tighten the screws. Screw head should be about 1,5 mm inside head holes. If you will tight them too much it will destroy plate at the upper part.
Release upper part and check if blade is not visible inside the filament hole. If yes loose the screws little bit.
I recommend putting some lubricant inside to keep the mechanism running smoothly.
