Espresso / Coffee Knockbox

thingiverse

I was looking for a knockbox for my espresso machine and was dissatisfied with the price of these. It's literally a container with a bar on top. To I decided to design one - how hard could it be. Update: I added an accessory box to hold all the parts for a Breville machine. Might also fit other machines accessories but no guarantees :) Update 2: Added a hole to store a goodcook thermometer for the milk temperature. Also added drain holes in all the pockets for the water to get out. I added small areas at the bottom of the accessory box to add little rubber feet if desired. Removed the thick knock-bar as it caused too much splash damage when knocking the coffee of the filter. The container is printed in 0.33mm layer height and 20% infill with 3/4 walls. The bar is the same but I used 10 top layers to strengthen the area I will be knocking on. Maybe it makes sense to coat this whole thing in plastidip to make it more water proof and easier to clean. We will see. Support: I printed the accessory box on its head without support. So the top surface is on the print bed or on the raft. Next time I would add support to get nicer curves inside the cavities. Especially the one for the double filter doesn't look great since it's fully exposed. With supports, it would look really nice. I'd also like to try to print the knockbar in something flexible like PU or Ninjaflex. It's pretty brutal and loud to knock on PLA. Speaking of the knockbar: It's printed with 10 top layers to make it really solid at the top.
