intensewalkera Wall mounted Spittoon - yes i know, gross, but i needed one

Spittoon to hang on the wall next to my treadmill in the garage. my garage wall beside my treadmill was looking a little bit disgusting the other day, more so after a bout of flu, ewwwwwwwwwwwwww, so man has 3d printer and man makes a spittoon as a solution. :-)
The base tapers to the centre from all directions,with a kind of drain hole, i am looking to use some recycling type milk carton, or something that is easy renewable, to collect the STUFF in. i will modify things a little once i find a suitable sump and once i have printed it.
it has a 6mm dia hole to hang it on a wall somehow
