caliper case

I made this case for my mituoyo caliper i put a foam inside with a cut out in the shape of my caliper 
for this you will need:

•  M3 x 40: 2x
• M3 x 5: 4x
• top case : 1x
• bottom case : 1x
• locking mecanism: 2x
• 10 mm thick foam board cut to form: 3x

I recomend petg for the locking mechamism becaus it is tougher.
