Ender-3 Filament holder tube
thingiverse
Made this to hold a wider wood filament spool - the tube prints well with:\r\n\r\nPLA material\r\n214C nozzle temperature\r\n20% infill density\r\n1.2mm wall thickness\r\n0.24mm layer height\r\n\r\nThe nut is printed at 102% scale, providing a slightly loose fit; printing it at 100% with high resolution would also work.
