Hello! I found myself in the need of a coffee maker, and since i didn't want to spend on one, i printed it, and it works really well.
This coffee maker consists of a funnel (made specifically for machine coffee filters) and a lid that goes on the top of a mug, with a tiny ring that prevents it from sliding off.
As a normal coffee maker, you mount the pieces as shown in the picture, and after you put your filter and your grinded coffee on top, you can prepare your coffee directly into the mug.
Print it in PLA or any food-grade plastics, and try to use a flow greater than your normal flow, to avoid air bubbles in between the layers. If you wanna go farther, you can give it a cold-acetone bath to smooth out the surface.
