NO SUPPORTS NEEDED This one's a longer print but can be reduced with a big nozzle and on some printers, vase mode (spiralize outer contour for my fellow cura peeps out there.)
this is a model that I made a LONG time ago for those bottle openers that mount to a wall and drop the caps, meaning they fall to the floor and are a pain to pick up or are in an annoying place to prevent it falling to the floor (above a table or low down meaning it's "not much further to grab the cap off the floor"). this model comes with a draining hole for all the different liquids that may end up in there whether it's rain, beer, juice of some kind or in some country's, tomato sauce. Simply place 2 screws/nails into wall where you want to mount it under bottle opener. (I place on wall and use a pencil to mark holes) then slide on and push down to secure. When full, slide up and pull out to remove. empty into bin and slide back on. have fun making this one folks!
