About this model

This spool weight is designed to perfectly fit Sunlu filament spools. It can also work on other spools that measure around 74mm internal diameter. The weight will fit entirely inside the spool and will stay in place due to the flexible fins around the outside. This makes the spool less bulky, prevents the weight from getting caught on things, makes installation/removal easier, and makes stacking spools with the weights inside easier. The standard weight is designed to fit AA batteries inside, but I have also included a hollow version that allows you to fill it with whatever you see fit. The cap screws on snugly to prevent anything from falling out while printing.
