Round-bottom flask stand

thingiverse

Round-bottom flask stand for 250 mL flasks. Empty flasks won't be very stable if this object is printed with standard filaments. Recommendation: Apply three small drops of hot glue onto the contact surface between glass and plastic, then press the flask into the stand. Remove the flask afterwards. The flask should then be much more stable. I also made multiple test tube stands, which can be found here: Version for 7 small tubes: https://www.thingiverse.com/thing:2460058 Version for 7 normal-sized tubes: https://www.thingiverse.com/thing:2719817 Version for 7 large tubes: https://www.thingiverse.com/thing:2460095 Version for a single large tube: https://www.thingiverse.com/thing:2460016
