Using the Phaser3D Sunlu Filament Dryer 3D Printer Mount is straightforward. First, pick the right version for your printer. If you have a Prusa MK2 or MK3, use the Prusa version. Just click it into place. For Creality or Tevo Bowden style printers with a 20mm V - slot top rail, go for the side exit version and bolt it on. If you have a direct drive printer like a converted Ender 3, choose the front exit version and bolt it as well. When using the mount with the Sunlu Filament Dryer, you can dry your filament and print at the same time. Keep an eye on the humidity in the dryer using the Humidity Sensor and Humidity Mount. After you finish printing, store the filament in airlock bags. Use the NanoVac Pump to remove air from the bags. Put a Humidity Sensor in the spool adapter so you can check the humidity when you're ready to print again. You might need to dry the filament again for the best results, but it won't take as long because it was stored in the bags. You can stack the filament bags on top of each other, but be careful of sharp filament ends or spool parts that could puncture the bags. If your printer nozzle gets clogged, use our nozzle cleaning filament. There's no hardware included with the mount. The Prusa Mount attaches like the original mounts, and the Creality/Tevo versions use the same hardware as your original mount. You'll need to reuse that hardware. And if you're handy, you can buy the STL file and print the mount yourself.
