When you order a kit of tools to build a Van's RV-12is, you receive a lot of various sized drill bits individually wrapped in clear plastic bags. I created a Caddy to organize the various sizes. Created in Fusion 360, prints nicely in PLA. I like it with about 40% infill but it would probably be fine with 15% or so.
