Recycling an old coffee can into an outdoor ashtray. Snaps down over the rim nicely. UPDATE 6/16: Made it a bit taller as the cig rests were slightly touching the open space for the collar. UPDATE: 6/20: Decided I also needed a little ring with spots to put half-smoked butts and a small tray for whatever. Do not need to Scale to Fit, just rotate 90 degrees. I secured it with a small zip tie.
