A minecraft mod that simplify the way to do floating items without doing all that armor stand stuff. This mods add this commands:
/floatitem help (gives information about commands and what they do)
/floatitem list (makes you know what items are floating in your dimension)
/float item place x y z id:name rx ry rz (places a new floating item)
/float item move type id:name x y z rx ry rz (makes an existing item move)
/floatitem rotate type minecraft:diamond rx ry rz (makes your item rotate)
/floatitem setitem type id:name id:name (replace an existing specific floating item with another item)
/floatitem remove all/type id:name (removes floating items)
if you don't specify the item's id the modify will be done in the nearest, in some commands there is an auto relevation of the existing floating items that will be suggested if you want to do the setitem command for example.
