50mL conical tube COOLER
Description
Summary Do me a favor and a favor to yourself and use the following link to MyMiniFactory. Thingiverse is a bad joke. Some of my designs just disappeared forever. The website has several other issues and the smartphone app isn't working. https://www.myminifactory.com/object/3d-print-232238 ===== Cooler for 50mL conical tube. Fill it up with water using the openings on the side and keep it inside the freezer until the water is frozen. After it we kept it outside the freezer with a conical tube inside the cooler for 1h. The temperature on "tube B" dropped almost 22°C when compared with the "control tube A". ===== If you'd like to support me you can post a make, comment and/or pay me a coffee at [PayPal](https://paypal.com/paypalme/paulorfo)
