Brain coral textured rolling pin

Maze-like meanders like brain coral, for ocean pottery and clay. Ridges and valleys of even width, winding everywhere.

Clay ~129 g Pro early access

A maze of meandering valleys, every one the same width, winding and forking between rounded ridges, the surface of a brain coral. Grown by a reaction-diffusion simulation, the same process that patterns real corals and animal skins. Roll it into porcelain for ocean-themed mugs, bowls and soap dishes, into polymer clay for sea-inspired jewellery, or into air-dry clay for reef terrain.

Made with our free texture roller tool in its Rolling pin style, not modelled by hand: we drew the pattern in code as a seamless picture, uploaded it, and set a sleeve 40 mm across and 100 mm long, the pattern raised 1.5 mm and repeated three times round and twice along. The zip holds the texture sleeve and the tool's own two rolling-pin handles, as two STL files, plus the pattern picture, so you can remake the sleeve at another diameter or depth.

Every sleeve in this set slides onto the same two handles: the core, 202 mm long overall, a handle with a 30 mm tube, and a cap that locks on with a quarter turn. Print the handles once, and after that only sleeves.

Brain coral textured rolling pin at a glance: every printed part with its size, print time, filament, print settings and the three steps to use it

What you need

4
  • About 129 g of PLA or PETG for the sleeve and both handles (about 34 g for a sleeve alone)
  • Something to texture: stoneware, earthenware or porcelain slabs, or air-dry or polymer clay
  • A printer that can print 207 mm tall: the core handle stands 202 mm on the bed
  • A little cornstarch, or a water spray for pottery clay, if it starts to stick

How to use it

5

  1. Print the sleeve and both handles standing on their ends, as exported, no supports. A 5 mm brim keeps the tall core steady.

  2. Slide the sleeve over the core's tube, push the cap on with its slots over the two lugs and turn it a quarter turn to lock.

  3. Roll the clay to an even thickness first: 5 to 8 mm for pottery slabs, 2 to 3 mm for jewellery and ornaments.

  4. Roll across once, in one direction, with steady, even pressure, and lift off at the end. Going back and forth doubles the pattern.

  5. Turn the cap back to swap to another sleeve from the set, and wash the sleeve in warm soapy water after use.

Questions about this design

How was the brain coral textured rolling pin pattern made?

With a reaction-diffusion simulation (Gray-Scott), run on a grid that wraps round the sleeve, so it grows its maze without a seam. It is the same kind of process that forms the patterns on real corals and on some animal skins.

Which glaze suits the brain coral textured rolling pin?

A glaze that pools in the valleys: a turquoise, a sea green or a coral pink over white porcelain. The ridges come out pale and the maze dark, like coral seen through clear water.

Does the brain coral textured rolling pin fit the same handles as the other sleeves?

Yes. Every sleeve in this set is 100 mm long with a 30.6 mm bore, and every zip carries the same core and cap, so you print the handles once and swap sleeves with a quarter turn of the cap. They also fit handles printed from the texture roller tool itself.

How long does the brain coral textured rolling pin take to print?

About 5 h 10 min for everything on a current printer at 0.2 mm layers: about 1 h 20 min for the sleeve and 3 h 50 min for both handles. Once you have the handles, each new sleeve is only the first part. The times are estimated from the parts' volume, not sliced.
