Dewalt ToughCase Utility Blade Holder

Dewalt ToughCase Utility Blade Holder 1


This is an insert for Dewalt Toughcases to hold standard sized utility blades. It should work in all ToughCase and ToughCase+ storage boxes. Each holder holds 15 blades give or take, depending on the thickness of the spring.

The blade slot is just wide enough that only one blade should come out at a time.


Printer: Prusa i3 MK3
Slicer: PrusaSlicer
Material: Inland PET-G
Resolution: 0.3 mm with a 0.4mm nozzle
Wall Lines/Perimeters: 2
Infill: Minimum 20% Gyroid. The higher infill percentage the stronger the part.
Notes: No supports needed


The holder accepts two 3/8″ x 3/4″ springs to hold the blades in place. My source was the Harbor Freight spring assortment item#67562. The springs should pop into place by compressing them and pushing them into the holes at either side of the blade bay.

To insert blades, push them into the blade slot and push the blade against the springs when it is at the bottom. Just repeat until you get about 15 blades.

To remove the blade pinch the blades and lift up with your finger or thumb (whichever is touching the outside blade).
