I keep utility blades in my skateboarding bag for applying grip tape and needed something to safely store the blades in.

This is a storage case for utility blades with a hinged lid and snap closure.
Designed for 20x 0.5mm thick blades, however the actual print will likely hold less.
The case has a centered divider meant to separate new and used blades, if desired (10 blades each).

Hinge Test Print Model:

Included is a test print model for the print-in-place hinge.
I recommend printing the test model first to insure that your printer is achieving adequate clearance. If you have trouble cleanly printing the hinge I recommend lowering the nozzle temp, reducing the flow rate, and reducing the print speed.

Print-in-Place Model:

This is the intended print design as it requires no further assembly after printing.

Recommendations/Settings:

• 100% infill for hinge strength
• Print hinge axis orthoginal to bed
• Sparse supports to help with bridging

Split Assembly Model:

I've also included a split model design in case the print-in-place model is too problematic.
The hinge can be assembled and glued post printing.

UtilityBladeCase_SplitModel_Case.stl
UtilityBladeCase_SplitModel_Lid.stl

I hope you find this model helpful!
