Prusa MK3 PSU cooling for Tukkari TS and other enclosures. SEE VIDEO HERE https://youtu.be/xPJshCr5V6E The Tukkari TS enclosure, in this example, for Prusa Mk3s does not include a PSU shroud between the PSU and honeycombe vent plexiglass side panel. This accessory in PETG provides a bolt on shroud to direct cool outside air to the PSU.and stops any air from the vent going into or out of the enclosure. In addition, there is a mount for a 40mm fan. The fan should be pointed to push cold air into the PSU vents (not suck air from the PSU). 12v and 5v (usb) fans are readily available. Without the fan running, i found the PSU became quite hot in use, even though the shroud ensured the PSU was linked to the honeycombe grill and outside air. With the fan running, the PSU casing did not exceed 33 degrees C during a 5 hour print (temp inside enclosure was 29, ambient air temp 21). Below the fan is a cuttout for the fan cable, and an X shape cable tidy anchor This could be adapted for any home made enclosure (Ikea Lack, or wooden enclosure), just cutting a vent in the enclosure side. Although the Zukkari already has the vents cut in the plexi.
