Vernier caliper case 100mm (4") - WIP

I needed a case to transport my 100mm analog caliper and I wanted to have a latch included in the geometry as well as filament hinges. I left some room to glue foam to protect the caliper but ended up not doing it. 
 

WIP:
The latch has worked fine for about 6 months as well as the hinges but I would like to improve the latch geometry because it can be hard to open when new.
