Comgrow/Sovol SH02 Filament Dryer 40mm Fan mod

If you have a sovol SH02 filament dryer, you know how annoying the fan is. This fever dream of a mod replaces the stock fan with an off the shelf 40mm computer fan and makes the dryer essentially silent.

You will need, at minimum;
A 40mm fan (must be 3pin with tach)
1x 40mm fan duct (printed)
2x comgrow base half (printed)
 

Optional but recommended- 
4-8 #6 2-½ inch wood screws from hardware store
some small twist-type wire connectors
A spare JST-xh connector in case the stock one gets damaged

The pinout of PC 3 pin fans is different than the stock- you will need to either swap or splice the wires on the 40mm fan to match the default fan pinout. 
If your fan doesn't have a tach wire, the dryer will shutdown. 

I'm sure i've left a lot out, i'll update this as I go. Feel free to post questions and I'll get to them as soon as i can.


Thanks for looking!
