Scallop shells, starfish and snail shells for coastal pottery and beach crafts. A beachcomber's handful, scattered.

A beachcomber's scatter: scallop shells about 14 mm across with radiating ribs and the two little ears by the hinge, bumpy starfish about 13 mm across and flat spiral snail shells about 9 mm, all at their own angles. Roll it into stoneware for coastal mugs, soap dishes and planters, into air-dry clay for beach-house ornaments and coasters, or into polymer clay for summer earrings.
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 tool prints the sleeve 1 mm shorter, 99 mm, so a printed sleeve turns freely between the handles. The zip holds the texture sleeve and the tool's current 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 made for the current handles slides onto the same two handles: the core, 194 mm long overall, a handle with a 27 mm tube, and a cap that locks on with a quarter turn. Print the handles once, and after that only sleeves.
The first picture is a 3D render of this sleeve on the clay it has pressed. The two photos are our own test print of the rolling-pin system from the texture roller tool, with a hearts sleeve: put together, and as its three parts.

Print the sleeve and both handles standing on their ends, as exported, no supports. A 5 mm brim keeps the tall core steady.
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.
Roll the clay to an even thickness first: 5 to 8 mm for pottery slabs, 2 to 3 mm for jewellery and ornaments.
Roll across once, in one direction, with steady, even pressure, and lift off at the end. Going back and forth doubles the pattern.
Turn the cap back to swap to another sleeve from the set, and wash the sleeve in warm soapy water after use.

Use a sandy speckled clay, rub a blue or turquoise wash into the shells and wipe the surface clean, then glaze with a clear matte. A light sanding of the high parts after bisque firing brings the clay colour back.
Three kinds: ribbed scallop shells about 14 mm across, five-armed starfish with a row of bumps, and small flat spiral snail shells about 9 mm across, mixed evenly over the sleeve.
Yes. Every sleeve made for the current handles is 99 mm long with a 27.6 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. These are the handles the texture roller tool makes today, so a sleeve you design yourself in the tool fits them too. The older sleeves in the catalog with a 30.6 mm bore need their own, bigger handles.
About 4 h 20 min for everything on a current printer at 0.2 mm layers: about 1 h 30 min for the sleeve and 2 h 55 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.
