(Scale is set to approx 4.5 inches assembled by default, scale up to desired size. Key in photo is 180% for both parts.)
Instructions below.

A cute turn key design for cosplay/whatever else, photo shows older version without bumpers and belt holes.

INSTRUCTIONS / suggestions:
-- Bumpers on side of key slide into the holes on the base, turn it around once inside to keep it in place.
-- Make sure to print the base at a higher infill than the key for the best result.
-- Print the key at a lower infill (10% and below). If it's too heavy it will lean down when worn.

-- If the base fit is too snug for key to turn, scale it up slightly (1% - 5%).
-- If the base fit is too loose, scale down slightly in similar increments. I have the tolerance optimized for a matte filament I was working with but some prints in basic filaments were harder to turn. If it's too loose, the key might jiggle around.

-- Use supports as needed. The base will need supports for holes at the bottom and i
