Open Crown Hat Block (Filament-Saving) – 58cm – 3D Print STL File

A 3D-printable open crown hat block, designed for makers who shape felt, straw, or fabric hats by hand. The STL file prints on any FDM or resin printer and gives you a precise, reusable block for consistent results, whether you're producing one hat or a small batch. What you get: an instant-download STL file, ready to slice — no physical item is shipped. Recommended for PLA, PETG, or similar filaments; a higher infill is recommended if the block will see repeated use. For personal and commercial use of the printed blocks. Resale or redistribution of the file itself is not permitted. At a 58cm head circumference, this specific size corresponds to a US/UK hat size of approximately 7 1/4 — handy if you're more used to sizing by hat size than by a tape measure in centimeters.
