I like to wash my ziploc and other plastic bags after use, but they're hard to dry properly given their propensity to lay flat and close. I designed this using 3/8" dowels (cut at 9.5" though I would recommend cutting them a little longer for bags the same size visible in the attached image. I used 3/8" dowels as the primary support because printing that part to the length required would have maxed out my bed's area and taken too long when dowels are cheap and available. I used 3 walls and 12 or 15% in fill, which was strong enough. I also used a brim for the "KeeperOpener"s because of the minimal bed contact
