Add a fan to your Sunlu Filament Dryer so the moist air can escape. Does it work to improve the filament drying process? We'll see. I just installed it today.
Things you'll need:
- Buck Converter
- 40mm box fan (any voltage that works with buck converter)
- Barrel jack male/female plugs
Instructions:
- Trace and cut out the fan port on the flat part of the back of the dryer. I used a marker and a hot knife attachment to melt/cut the plastic. I drilled and tapped M3 screw holes for mounting the fan.
- Solder one male and one female barrel jacks to the input side of the buck converter.
- Solder the fan to the output side of the buck converter.
- Test that everything works.
- Plug in the 24v dryer power adapter to the buck converter and set the output voltage to allow a very low fan speed (or any preferred speed). Output voltage pot is accessible when case is closed for future adjustments.
- Place finished buck converter in the case, taking care to route wires through portal.
- Zip tie, glue, or otherwise secure lid of case.
- Mount fan to filament dryer.
- You may need to use a sharp knife to reduce the size of the barrel plug that interfaces with the dryer.
- Plug everything in and let me know how it works.
