Bottles-2-Hourglass #washyourhands

prusaprinters

<p>This is a simple connector to make a DIY hourglass made from common plastic bottles. Use it to make sure you wash your hands long enough every time (at least 20 seconds).</p> <p>Ideally, you can use small plastic bottles (eg. 250ml) or cut large ones to size (like I did, since they were all I had and I didn't want to leave my quarantine just to buy some smaller bottles). Close the ends with a custom printed part or any thin sheet material that can be cut and glued to the bottle.</p> <p>For the medium I used salt, but use whatever you have. Add as much medium as needed. Does not work with fluids.</p> <h3>Print instructions</h3><p>I used Prusament ASA (260°C/108°C) @ 80mm/s with print cooling fans always on. Does not need support.</p>
