  • Small 3D printed hopper for the EK43 grinder

    Our little kitchen is crammed with cooking equipment and giant roaster, a huge EK43 grinder and a big espresso machine. A few months ago I bought a Londinium R lever machine. The machine is still unpacked but it will be installed in the coming days. The machine has a huge lever that makes the machine…

  • Design a toy car in Fusion 360

    3D Modeling is a very powerful technology for designing and prototyping products. I recently prototyped some espresso dosing funnels. For prototyping I used CAD program Solidworks. This did unfortunately not natively run on my Mac but I was able to run it in a virtual machine. This approach however did result into many crashes and…

  • Tiny Fluid Bed Roaster update

    (movie by Frans Goddijn) Last week we updated the Arduino software of our air roaster prototype. Tije fixed the new safety switch that I brought along. In case of software failure, you want to switch off the heater and keep the blower active in order to cool the beans and prevent overheating of the blower…

  • 3D printed espresso dosing funnel

    Recently I wrote about a 3D printable espresso dosing funnel that I designed. Yesterday the print of the design was finished. I wanted to have a fully functional prototype, therefore I chose to print it in ABS. That printing material (‘filament’) can withstand up to 100 degrees celcius.

  • Simple affordable-for-all fluid bed roaster

    Tije de Jong, Frans Goddijn and I are thinking of a small simple affordable-for-all fluid bed home roaster for coffee. The roaster is supposed to roast 200 grams of coffee and work with the Artisan roast software. Furthermore the machine is intended to have PID control and adjustable airflow. This combination of things would make…

  • Espresso dosing funnel design

    Dosing the coffee in the espresso portafilter basket and distributing evenly can be difficult. A small funnel can help to ease this proces. Tije made a beautiful one for me and there are funnels on the market like the IDR dosing tool. I’ve recently learned how to draw in 3D and I thought it was a good exercise…
