These are 3 variants of the same idea, specialized drill case holders. Two have standard 1/4" holes, one has varying hole sizes.
I usually use a 0.6mm nozzle for this kind of print with very little infill. The holes may be undersized just a tiny bit, but you can ream them out with a 1/4" drill bit by hand for a perfect fit.
