Coffee Monsta' !!!

EATS THE COFFEE, not the foil lid. This thing is for extracting coffee grounds from used K-cups and composting them as they make excellent fertilizer. It's a great way to reuse spent coffee grounds instead of individually packaging them. You'll need a wide-mouth style mason jar to collect the used coffee grounds. Add them to your compost when the jar fills up, a little bit each day adds up quickly. This edition uses 12 grams less plastic than previous ones, making it print much faster. I've included necessary supports with central raft so you don't have to worry about central supports breaking off the build plate or wasting plastic printing a full-size raft under the entire part. My duplicator 4 can 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, but will still work. If printing straight on aluminum, turn on the fan prior to the first layer of printing. I use a 12V computer fan with a 9V adapter and an aluminum build plate at 80C without glue or blue tape. The secret technique I've discovered that works for sub-2h prints is that PLA sticks to the build plate at 80C, after the print is done, 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. For 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.
