About this 3D model

A high efficiency, adjustable flow, part cooling duct for Anycubic Mega series printers (i3 Mega, Mega S & Mega X, & easily adapted for other makes). When set to 100% with a high flow 5015 fan, this gives much more rapid cooling than the standard fan. This setting is suitable for printing very small parts without Z-hops; however, at 100%, this may be far too much cooling for larger projects, so a variable baffle is included to give a much greater range of cooling efficiencies than can be obtained by fan adjustment alone. The duct cools the back and both sides of the print, using shaped venturi that provide laminar flow air curtains above the main turbulent cooling flow to reduce cooling of the heatblock whilst maintaining efficient cooling of the printed part. For longevity, it is recommended that a 5015 fan with dual ball bearings be used, but this is not essential. It takes influence from (but is not based on) the cooling duct used by the Prusa i3 Mk3s. © 2020 Eleanor Xanthe Ellis / Cyan Ellis Ltd., some rights reserved.Licenced under the Creative Commons Attribution Share-Alike 4.0 International licence (CC-BY-SA)
