modular 5ml vial stand

A modular stand for holding the widely available 5ml plastic vials.

It can be placed horizontally on a flat surface, or vertically with an additional base part.

The clearances are pretty tight on the dovetails. It works well on my printer at least, and gives a pretty tight fit, that doesn't just slide apart on its own, but can still be taken apart if needed. But it might end up too tight or too loose depending on your printer. You might be able to adjust the extrusion ratio a bit either way, if it's too tight or too loose.

I print these quickly at .2mm layer height with a single perimeter with .8mm extrusion width, and no infill.

These models are modeled with fscad, a programmatic CAD framework for Fusion 360. See https://fscad.org
