Summary
This is a remix of the EAB utility blade.
Motivation:
I found that the original EAB when printed in PLA would have the locking mechanism snap off very easily. There was also no way to flush mount the screw and retaining nut.
Overview of changes:
Re-designed the locking mechanism for PLA. (Moved it over and reinforced the piece)
Modified the tolerances around the blade swivel for a 0.4mm hotend.
Reduced size of pocket clip.
Added inset holes for M3 screw and M3 nut.
Chamfered the blade cover.

30 Notes:
Printing PLA at 0.2 resolution I had some difficulty with tolerances. This lead to the blade not moving smoothly. I would suggest 0.1 resolution, but it takes longer. At 0.1 resolution in Cura, it would have taken somewhere closer to 3-4 hours. At 0.2 resolution, it took 2:25 hours.
