Large Thread Spool Adaptor

thingiverse

These are adaptors for using large spools of thread on a Singer sewing machine, designed to accommodate tall spools that allow the thread to clear the bobbin when winding. Each size features one version with a bulge and another without, serving a distinct purpose: the bulge creates a tighter fit inside the spool, enhancing its performance. I've only printed the taller model with the bulge. To produce these adaptors effectively, it's essential to minimize infill settings (10%-15% is sufficient). Printing at a layer height of 0.3mm yields excellent results.
