Inspired by 247zero beta1, this auxiliary fan unit is guaranteed to destroy your eardrum.
Has a smooth interior instead of 247zero's square shaped hole.
Ideally print with 2 outer walls and use a height range modifier to change the first 5mm to 100% infill.
An extra 12mm spacer is needed to not limit x-axis travel.
Can be used with 4020 silent fans alongside dragon burner to achieve similar performance to 2x5015 toolheads.
The author marked this model as their own original creation.
