Buy the decent quality pieces you want, figure out what size box you need to keep them in plus a bit bigger for maybe a couple of additional tools in the future and enough space above and below for foam padding then buy a wooden box and foam to fit (Amazon has a big selection). You can even make cut outs in the foam to locate each tool.

Voila!
For example my vernier, not a cheap one, came in a naf plastic box but a couple of Euros and and 10 mins work and it now looks much better.
