A true top hat needs a straight-sided cylinder block — tall, vertical, and precise, since any wobble in the crown wall shows immediately in the finished hat. Formillionaire’s cylinder and top hat blocks are modeled for exactly that straight-sided accuracy, available as single-piece blocks and as multi-part cylinder blocks with a separate brim plate for combined crown-and-brim projects.
Extender Plates for Fine Sizing
Because a cylinder block’s diameter is fixed at print time, the range also includes cylinder hat block extender plates — thin spacer discs that sit between the block and the felt to nudge the effective crown size up by a few millimeters without printing an entirely new block.
What’s in the Range
- Cylinder (top hat) hat blocks, single-piece
- Multi-part cylinder hat blocks with matching brim plate
- Cylinder hat block extender plates for fine size adjustment
Trace Your Own Top Hat Brim
Top hat brims are flat and narrow compared to a western brim, which makes them a good first project for the brim plate generator — trace the outline, dial in the taper, and export a plate sized to match your cylinder block.
