About this model
Real demand for a vial/bottle holder sized to a specific item diameter, height, and count -- a common long-tail pattern where the exact combination of size and quantity isn't served by generic racks.
Fit notes
- 1mm clearance per pocket for a neat (not press) fit around each 18mm vial
- Pockets are 30% of vial height (18mm deep) -- stabilizing, not full-height enclosure
- 4×5 layout (closest-to-square arrangement for 20 items)
Printing & use notes
No print settings (layer height, infill, supports) are specified for this model — use standard settings for your printer and material. See the validation section below for what has and hasn't been checked.
