These two cases are for hex drill bits with a standard 1/4" hex shaft. Both of these hex (Allen) bit sets can be bought on eBay or Aliexpress. One case holds 7 bits and the other 8. They are also not the same height.
These were printed in PETG but PLA should be fine too. You can print them with 15% infill or hollow with two perimeter walls. The models are optimized for 0.3, 0.4 or 0.6mm nozzles.
