Sturdy Dual carriage J head Bowden with 40mm Fan mount

thingiverse

To enhance cooling of the J-head's peak blocks, add up to two 40mm fans without compromising carriage stiffness and preventing print failures. Additionally, an extra shroud helps maintain cool air around prints, particularly for ABS materials. As I upgrade my printer, I am in the process of testing this feature. Print with a layer height of 0.25mm or 0.3mm and a minimum 33% infill for optimal results.
