CR6 SE 4020 light fan adapter

thingiverse

Provides a lot more airflow so the fan doesn't need to run at 100% all the time (40% is about the power of the original fan). It also saves you ~70g of moving mass, so you can accelerate faster. Combine that with the shorter minimum layer time and this mod will save you quite some time. It is required that you remove the upper part of the original 4020 fan duct and replace it with the printed part. You might also need to change the polarity on the fan's plug, but check that for your specific fan. Just use M3 screws to mount everything Please note that this is a work in progress and the design might be further iterated
