hey :> this is a rework of a door i've made in 2019 ! i've always been proud of it but it was absolutely ABSOLUTELY massive, and now i've made it much smaller, from 24 long, 16 wide, 24 high - 9216 blocks, to 20L x 10W x 17T - equaling 3400 blocks. In terms of speed, it closes in 0.9s and opens in 1.2s if i did my math right(lmk if i did something stupid)
this door has targets, but no slime/honey blocks or observers are in it.

the first download link will download a map with just the door itself in a void
the mega download link will download the NBT file which you can then summon in any world anywhere with a structure block
