PRUSA i3 MK2.5S Fan shroud FIX remix

prusaprinters

<p>Asthetic modified version. &nbsp;Print in ABS. This has break away area on bottom between nozzle ducts that needs does need to be snapped out. Do not remove block</p><p>The original FIX model ( v1) was derived from PRUSA production printer fan nozzle duct and then modified to BLOCK EXCESSIVE AIRFLOW after upgrade 2.5S Kit. Previous models I put up work and still are valid.</p><p>This IS the PROVEN fix for the THERMAL RUNAWAY issue due to nozzle and heat block cooling too rapidly because of excessive air flow across the heat block.</p><p>I spent numerous hours figuring this out , wasted several rolls of filament . I was not going to let this deter me from continuing my hobby of printing and made me continue to resolve this issue… so when I figured it out I made the corrected part and published the solution on 14 Feb 2021 in the PRUSA forum.</p><p><a href="https://help.prusa3d.com/en/article/thermal-runaway-i3-series_2131#_ga=2.56002984.22460516.1634337160-558235080.1633703836">https://help.prusa3d.com/en/article/thermal-runaway-i3-series_2131#_ga=2.56002984.22460516.1634337160-558235080.1633703836</a></p><p>My previously published models &nbsp;are cited and still valid.
