Frequently asked questions

A1: Yes. It supports all filament spools with 72mm within 1kg.

A2: The dryer box is not completely sealed to allow moisture to escape. This is normal andexpected.

A3: Our products has been tested at an ambient temperature of 25℃. If your ambienttemperature is lower than 25℃, it may not reach 70℃. You can try wrapping the outside ofthe drying box with an insulating sponge to reduce heat dissipation and increase the uppertemperature limit (maximum limit is 70℃).

A4: We have tried to make the spool holder be compatible with most filaments. Butunfortunately, the stock spool holder can't fit all the filaments. Here is the solution: You canreplace it with a 3d printed one so it will fit your filament. Or you can send a request mail to support@gratkit.com then we will send you the STL file so you can print it.
