**IMPORTANT: [Get the latest updates for this model here on PrusaPrinters](https://www.prusaprinters.org/prints/8775-prusa-i3-mk2s-adaptor-for-40mm-silent-fan). In 2021, all updates and uploads of new models were moved to PrusaPrinters, of course still free and under the same conditions... :)** [Jure Korber](http://www.thingiverse.com/JKSniper/about) made this really nice design for a 40mm Prusa fan adapter. To fit a 40mm fan on the Original Prusa i3, the fan has to bend outwards to avid collision with the left X axis motor mount. Jura made it tilt upwards as well, saving vertical space and better intake of cooling air. I was looking for a minimal design, but still with a strong construction. Editing the original STL file is nearly impossible as it has a lots of curved surfaces. I decided to start all over with the fan specification and the twist... and ended up with a design very close to the original :-) **What has changed:** * Smaller 40mm fan base and re-enforcement for
