Alternative fan mount, fan relocation for Sovol SV02

thingiverse

This is a relocation fan mount for SV02 double in hotend, optimized to sequential print and ASA/ABS filaments. High shrinking materials can't tolerate parasitic airlow without inmediate warping. This setup produces significantly less airflow to model than original setup. Part cooling fan moved to bottom of hetbreak fan, in order to keep free the right side of extruder. It is optimal if you want to print more parts sequentially, in that way you can place your parts much closer to each other if the nozzle is near to one of corner of extruder assy. For hotend cooling I use a 24V blower, 4020 size, but speed is halved with a 220R 2W serial resistor to reduce noise and unnecessary amount of air flow. As part cooling fan I reused one of stock fan, 4010 size 24V blower Furthermore, you should 3pcs of 3mm threads into printed part to prepare it to keep hotend fan. Original nozzle was quite low profile, I changed to normal height one, with 0.5mm diameter. To install part cooling fan, you have to change stock nozzle, mount is designed for higher nozzle Part list 1pc 4020 24V blower 1pc 4010 24V blower 1pc 8mm M3 screw 3pcs 20mm M3 screws 3pcs 6mm M2 screws (reused from SV2 orginal hotend) 1pc 220 Ohm 2W resistor (for fan slowdown) 1pc normal height nozzle
