Accurate Coffee Tamper

It allows the person to achieve adequate tamping pressure while using little force.

The mechanism takes over and jabs at the coffee bed with precise, repeatable and uniform pressure.

Consistency is the most important part of tamping – like with any aspect of coffee making, 30 lbs might be the best amount of tamping force for some coffees but not for all of them.

Although the suitcase scale is not required for the Tamper use, it is recommended, because is easy to embed it in this project and measure the applied force while tamping.

The bottom surface of disc Tamper is the only 3d printed part that comes in direct contact with ground coffee. If you have any concerns about this, cover the base of the tamper with a disc made of aluminum wall can for example.

Additional Parts:

• Suitcase scale, like this cheaper one: https://www.ebay.com/itm/Portable-Fishing-Digital-Weight-Electronic-Pocket-Hanging-Hook-Scale-40kg-10g/131876388393?hash=item1eb471fe29:g:hlkAAOSwRgJXhiIq
• I use a Phillips screwdriver for the handle. Any 6mm metal rod could be used.
