1.5 mL or 2.0 mL Eppendorf tube holder

thingiverse

This is a tube rack that securely holds standard 1.5 mL and 2.0 mL tubes microcentrifuge tubes. I liked MS3FGX's microcentrifuge tube rack but found that when I pushed down on tubes to close them, it made the whole thing flex down and it didn't fill me with confidence for my expensive PCR reagents. Being the person I am, I borrowed this idea and over-engineered the crap out of it: Now more stable and resistant to flexing! The tips of the feet are truncated to eliminate the short layers and melting/warping that accompanied them! Little cut-outs at the front of the holder makes flipping the lids easier! Tabs on the base so that you can tape or blue-tack the holder to your bench — no more knocking stuff over with your sleeves! The printing time for my remix is longer than the original (38 min vs 26 min at 75 mm/s), but I feel it's worth it for a more robust and usable object. Print Settings Rafts: No Supports: No Resolution: 0.2 Infill: Any How I Designed This Not much to say about the redesign, except for the tape/blue-tack tabs. There is a hole going through the tabs that you might think is for screwing the holder to the table, but it's actually there for blue-tack. When you push the tab down over a blob of blue-tack, the excess will mushroom out through the hole. This means that both the stickiness of the blue-tack and the interference of the blue-tack mushroom are keeping the holder in place. Changelog 22 Feb 2016 Initial release.
