Hario v60 Filter Holder (supportless mod)
thingiverse
Just a quick mod to allow the source design to be printed without supports, which simply involved removing one of the two decorative holes. Print on the front face with the hole down. The top gusset will bridge over just fine with no support at all if your printer has a halfway decent print cooling fan. The surface will be a little rough, but it's on the inside anyway and IMO it's worth the plastic and time savings. I also ran the file through NetFabb's automatic repair, as the source file had some broken geometry.
