This is a dust remover for the Yerba Mate herb.

V2: I finally got to print it!

There is still room for improvement, so when I get the need to print anotherone, I'll modify it to try and keep fixing stuff.

THINGS TO NOTE: Be sure that you have a really good retraction setting to prevent from stringing when printing the despolvillador, otherwise you might have to finish some holes with a file, because applying heat to the grill may deform it. Printing at lower speeds might help too. Also, to prevent the big seam line on the cup, you could add the fuzzy skin setting to have a more even finish.

 

Here is a list of what has changed:

  • Rounded corners on top and bottom
  • Made threads easier to engage
  • Made the dust remover grills smaller and thinner to print faster and let only the small grains of dust out, while keeping the bigger yerba pieces inside
  • Made the gap between cap and cup bigger for an easier grip
  • Made the little tab extend outside the cup for a better grip
  • Added a flange where the inner top of the cap sits (terribly failed)
  • Added flanges on the edges of the cup and cap for a better seal
  • Made cup thinner and a little bit longer

And, here is a list of what could still be improved:

  • Find a way to prevent Yerba from accumulating between the cap and the despolvillador (at the threads)
  • Improve threads for a safer feel when screwing
