These printed parts let you install Prusa's MK4S 5020 blower part cooling fan shroud - a slightly modified version, that is - on the Sovol Planetary tool head “high flow” variant as shipped on the SV06 Plus and SV07 series.
(Note: I don't have either of those machines, but rather a Sovol SV01 Pro upgraded with an SV06 Plus tool head.)
