E3D V6 3 Fan Shroud

thingiverse

I began with 340312 and 1973156, merging them into a single design. I liked the internal structure of 340312 for heat sink airflow and the dual fan setup of 1973156 for print cooling. However, I encountered issues when snapping on and off my heat sink. The parts would frequently break on the sides, so I added reinforcing ribs to increase their strength. Next, they would crack at the top rear section where it was extremely thin, prompting me to add a back plate for added support. I redesigned the clamp area to resemble a split shaft collar rather than a snap-on/snap-off design. This modification required (2) 3mm x 20mm socket head screws and (2) 3mm nuts. The sides feature small guides that hold the housing and clamp tightly against the effector. The two side-mounted cooling fans were initially positioned too high, interfering with my effector. I lowered them by approximately 4mm to resolve this issue, also needing to trim 4mm from the air guide bottoms. This three-fan shroud accommodates (3) 30mm fans: one in the rear for heat sink cooling and two on the sides for printed part cooling. Secure the fans using #4 sheet metal screws, 3/4" long, with a pan head. When installing the two side-mounted fans, be aware that if you use the top front screw hole, your screw will slightly engage the clamp, helping to hold everything together. Just remember to loosen these two screws before attempting to remove the clamp. This design was printed in ABS due to its intended operating temperature of 225 degrees, using a 0.2 layer height and 50% infill.
