Coffee Monsta' !!! by dbibeau

EATS THE COFFEE,...not the foil lid :O
This thing is for extracting the coffee grounds out of used k-cups for composting, as coffee grounds make excellent fertilizer (and cost a lot to individually package so why not reuse them??? : )
You will need a "wide mouth" style mason jar, then just add the spent coffee grounds to your compost when the jar fills up, as you can see in the picture, a little bit each day adds up!
This edition uses like 12 grams less plastic than previous editions so it prints waaaaaaay faster...
I've included the necessary supports with central raft so you don't have to wonder if the central supports will break off the build plate, (and don't need to waste plastic printing a full-size raft under the entire part)
My duplicator 4 will print one in about 36 minutes at .4 resolution with a fan, if you don't use a fan it may start to twist the tip a bit, but will work.
If printing straight on aluminum, turn on fan prior to first layer of printing, I use a 12V computer fan with a 9V adapter, aluminium build plate at 80C no glue, no blue tape...the secret technique I've discovered that works for sub-2h prints is that the PLA sticks to the build plate at 80C, after the print is done, just wait about 8 minutes for the build plate to cool down below 42C, and the print naturally contracts then pops off the build plate with no effort...
Over 2h prints, use blue tape at 80C, then when the print is finished, "preheat" the build plate to 110C and use a thin sheet of metal to spatula up the plastic part from the blue tape and set the whole thing on a sheet of glass to cool (like a cookie)
like the 2 derivative of rev41 68mm edition 'force' scaled,http://www.thingiverse.com/thing:929489
and rev49 for 68mmhttp://www.thingiverse.com/thing:934185
nice work : )
