Case for Small Hole Bore Gauge Set

I purchased a generic “Small Hole Bore Gage Set” (3-13mm or 1/8" to ½") from Aliexpress. I use these for precise measurement of hole diameters on the lathe. They came in a flimsy red pouch, so I designed a tiny case to store and protect them when I need to take them to the Hackspace.

It worked well for me in PETG. 

Infill 40% or more. No support needed. 

The lid is a snap fit, it works well on my printer, you might have to sand it a bit or tweet the tolerances to get a consistent fit.

I can provide the parametric Fusion 360 file if you want to modify.
