Insipration

One of the lesser-discussed challenges in 3D printing is the accumulation of empty filament spools. For hobbyists and professionals alike, these discarded spools can quickly pile up, taking up storage space and contributing to plastic waste. While many manufacturers design their spools from durable materials, the reality is that they are often not recycled or reused effectively. In response to this problem, the industry has introduced refill coils—spool-less filament bundles that minimize plastic use. To make these coils functional, a refill spool holder is used. This simple yet ingenious accessory not only reduces environmental impact but also enhances efficiency and convenience for everyday 3D printing.
