…Please be sure to hit like & post a make, I'd love to see your prints!

EDIT: Please note, the hinges are elements from the original design & are not my work, yeah they’re a bit tight & no they’re not that great, but they do work. If I come back & do a revisit to this I’ll definitely change them & make them better. 
 

Remix of the linked case model, I made some changes to accommodate slightly different tools available on Amazon with a squarer base to the handle that didn't fit the original shape, plus blades that measure 3.2mm diameter not 3mm.

Also added a recess for the latch & increased the width of the blade holders so they're stronger & don't break so easily. The tool tip cutout is also slightly changed.
