NMR tubes stand with a place for flask

Description

This stand was designed to hold 12 NMR tubes (5 mm diameter) and if turned upside down it can hold a flask. It is useful for round bottom or pear-shaped flask of volumes from 10 to 100 mL. The top part can be used to imprint some text like name as you can see from included photos. 

Printing

The stand can be printed in the normal standing orientation if your printer is capable of bridging 1,5 cm gap. It can be printed using regular PLA, however TPU is better option due to its larger coefficient of friction, thus flasks are held more securely. Ironing makes the top surface very clean looking.

Conclusions

I’ve already printed many of these stands and friends and co-workers working in chemical laboratories like them a lot. You can personalize them by including their name on the top surface.
