Over time, the 3D-printing filament passing through the fixed holes in the filament spool holder tends to break off on its own. The primary reason is that the filament remains under constant stress as it passes through these holes, eventually leading to breakage—this effect is particularly pronounced with matte-finish filaments.

Most filament spools come in various shapes and designs, so most commercially available filament holders are only compatible with one or a few specific spool types. In contrast, the filament holder I designed is nearly universally compatible with all spool formats, albeit at the expense of aesthetic appeal.

For printing with 95A TPU, we recommend using a 0.8 mm nozzle and following the material’s recommended temperature settings.
