Atari ST Floppy disk supports
thingiverse
There are 2 heights: Tall=20mm Short=17.5mm This should accommodate all types, the short being for long button floppy drives. Not Slotted=Solid object Slotted=a cross across the top to aid getting it in the hole in the ST mainboard. The pictures better detail the difference between slotted and not slotted. Also now with or without a chamfer. Prints fine at .2mm, but at .1mm if you get stringing, lower your filament temp. Un-chamfered is probably your best bet as is closest to the original.
