Introduction: Nice Little Coffeemaker
For many years we made coffee extract with the old coffeemaker we inhereted from our parents. Everybody likes the coffee so much, but such pots are rare...so I designed a printable one. Open to everybody. Making good coffee extract without a machine, that's the promise!
Step 1: It Consists of Three Parts: Pot, Filter and Cover
Step 2: Here Are the STL - Files
Printed in PLA works well. You can also choose another food safe material such as PET. Preferably without possible toxic colorants.
If you can't print it yourself, well go to www.3dhubs.com and upload the stl - files. Then you get a list of printer hubs in your neighbourhood, with all prices. The hub of your choice is asked for consent. Once given you can pay to 3dhubs and your hub starts printing. After a few days you can make an appointment with the hub to collect your coffeemaker. If you are happy with it, 3dhubs pays the hub and you can give a review.
To get the pot watertight asks for a good print quality. It is important to print at slow speed (<30 mm/sec) and no fan the first 5 mm. and with a little overextrusion. Check the quality by filling half with water of 70 degree C and place the cover on the pot.
Step 3: How to Make Coffee? First a Bottomlayer
Make the bottom of the filter a little wet and put a coffeepad or a piece of filterpaper over the holes in the filter.That's better for your health and prevents grounds in your coffee extract.
Step 4: How to Make Coffee? Then the Ground Coffee
Fill the filter with standard ground coffee till the inner edge.
Step 5: How to Make Coffee? Three Times a Little Water
Put a little hot water over the coffee and let it swell. Do that two more times. So all coffee is wet and ready for the next step. Mindfull coffee!
Step 6: How to Make Coffee? Two Times Full of Water
Fill the whole filter with hot boiling water and place the cover. Wait till all water has gone through. Do it one more time.
Step 7: Coffee Is Ready to Pour Out
When all the water has gone through, place the cover on the pot and pour out. Some drinks it straight as a ristretto or espresso, but many likes it best with hot water and/or hot milk. The extract can also be used the next day or later when stored in the fridge. Preheating of the cup is advised. Enjoy your coffee!
Step 8: Some Remarks About the Temperature
The temperature is near the edge PLA can have. Placing the cover while pouring out the hot extract prevents the pot from distortion.
The ideal temperature of making coffee is about 94 degree C or 200 degree F. For excellent results the first waters (step 5) need to have this temperature. For Step 6 you use hotter water because the grounds had already a little cooled down.
The advantage of the new pot compared to the old one is that the warmth is contained better in the filter. And the holes don't get clogged. So we use now only this nice little coffeemaker! Sorry for the old one.
We have a be nice policy.
Please be positive and constructive.
