Tiêu đề Miếng đệm ống chỉ Sunlu 500g Tóm tắt Giúp giữ các

I primarily use 500g filament spools from Protopasta and I wanted a way to keep the spool centered in my Sunlu Heater Drybox when in use. Because the heater is designed for 1kg spools the smaller spools tend to move around a lot inside the heater, especially when the filament gets low. This spacer should help to align the spool until it's empty.
