This is a cradle with stand for Amazon Echo Dot v2. Cradle can be used alone without the base. The bell part inserts into the bottom of the base, this should be a good friction fit.
Minimum supports are needed when printing the cradle where there is a gap for the USB/Audio cables, otherwise no supports should be needed with proper layer cooling.
Set your extrusion width to 0.4mm to print this design.
UPDATE 1/5/2017: Added "cheesy" cradle
I printed this with layer width of 0.2mm and extrusion width of 0.4mm
