Hat Maker Accessories & 3D-Printable Hat Blocks
Every hat block, brim plate, and shaping tool in this catalog starts life as a digital file — a millimeter-accurate 3D model you print yourself, then finish by hand. That's the core idea behind Formillionaire's hat maker accessories: instead of waiting weeks for a turned wooden block to ship from a specialist workshop, you download an STL file sized to an exact head measurement and print it on any FDM or resin printer, at a fraction of the cost and lead time of traditional millinery hardware.
The range covers the tools a milliner or hat maker actually reaches for at the bench: open crown blocks for fedoras and western hats, cylinder blocks for top hats, pork pie and sugarloaf crowns, cattleman and gus-style cowboy shapes, plus the smaller supporting hardware — brim flanges, extender plates, pushers, tollikers, conformateurs, and hat stands — that turn a raw felt or straw hood into a finished, well-blocked hat. Sizes are specified in centimeters so you can match a block to a real head measurement rather than guessing from a generic size chart.
Because each block is a 3D-printed hat making tool rather than a mass-produced one, sizing is flexible: a milliner working across a range of head sizes can print exactly the blocks they need, when they need them, without keeping a full shelf of wooden originals in stock. That makes this collection equally useful for a home hobbyist blocking their first felt hat and for a working milliner scaling up a small hat-making studio.
Browse the full range above, or use the brim plate generator to trace your own custom brim outline and print a plate sized to your own pattern.
