Finding myself with either a pile or a bag of floss picks to grab from each evening, I wanted a holder that would be compact and out of the way, yet easy to grab a single pick from. This is what I came up with to hold 10 picks while fitting into the corner of a shelf in my medicine cabinet.

Initial print was PLA with 10% infill, .20mm/speed setting in PrusaSlicer. Higher density infill would give the base more heft and therefore probably a more solid feel that might stay in place better, but even 10% infill allows easy removal (and insertion when refilling).
