Filament spool

thingiverse

For those with limited printer space, I designed this filament spool to fit snugly on smaller surfaces (mine is 15cm x 15cm x 22cm). My goal was also to incorporate anti-slip features at the bottom to prevent the spool from shifting. After researching online, I found several designs featuring flat bases along the sides, but they didn't work for my filament type. On the other hand, the ones that were suitable for cartridges were too bulky for my machine. The Simple Filament Spool (v3.2) has been a reliable solution for months now, but its rounded bases proved ineffective for me. To prevent the spool from toppling when moving the cartridge, I added a bolt and nut system to secure the sides in place. This design should benefit both owners of compact printers and those with larger machines that struggle with slippery surfaces.
