50 ml conical centrifuge tube holder (single)

thingiverse

Here's a simple holder for a 50 ml conical centrifuge tube, part of my 3D printing labware range. The goal was to create items that meet certain criteria: they must be functional, holding tubes securely upright; use minimal plastic, making them quick and cheap to produce; require little or no supports; take up as little bench space as possible; and can be easily modified and combined to make custom labware. Note that the new "v2" cross base design, unlike the previous triangle spoke base, prints better due to increased contact with the bed.
