anet a8 hot end fan gasket

by remixing the extruder fan spacer (https://www.thingiverse.com/thing:1798669) i designed this gasket.
it is available in 3 versions
V1 gasket only
V2 gasket and spacer
V3 four spacers (totally unuseful i think ;-) )

i installed it between heatsink and fan with the aim to reduce noise )but anet a8 is very noisy and i do not have the necessary instrumentation to certify i have reduced the noise)
