Remix of Tony_G:s Can Handle, lengthened the handle to fit "tall" 500ml cans.

Scale to your liking, but fits a standard 500ml can when scaled up by 2398.4% or to 176.4 x 113.2 x 18 mm.

Update

You may want to make it slightly, slightly smaller (approx. 2395% ?) for a tighter fit, but the exact amount could vary between materials and infill. I've discovered it struggles to hold on to some cans as long as they're full. An alternative is to add rubber or some other "grippy" material to the base grooves.

It should print without any problems laying down.
