Planetary Gear Filament Holder (No Hardware Required)

Many filament holders require the purchase of bearing hardware, which is inconvenient, and some bearing-free holders lack smoothness,

so I designed this planetary gear holder. This holder is exceptionally smooth, requires no supports during printing, and no hardware for assembly. It can be placed on a 5.8L rice bucket to enable dry filament printing and storage!

2024/10/10: Based on your feedback, I've added a tighter planetary gear model. The gear gap is smaller and tighter, making derailment less likely. However, the first layer is more prone to adhesion, so adjust the "elephant foot compensation" parameter accordingly when slicing. Users with high-precision printers can try printing this version. Below is a GIF of the new, tighter planetary gear in motion—smooth even without lubrication.
