Coiled ammonite fossils in pitted stone for pottery, terrain and kids' crafts. Ribbed whorls in a log spiral.

Six ammonites on every repeat, about 12 to 19 mm across, each coiled in a growing spiral with ribbed whorls and a pressed line between the turns, set in a lightly pitted stone. Roll it into stoneware for mugs, bowls and planters with a fossil look, into air-dry clay for fossil-dig kits, museum crafts and terrain, or into polymer clay for pendants.
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.

Yes, kids love it. Texture air-dry clay, cut it into rough stones, let them dry and bury them in sand. A brown or grey wash rubbed in and wiped off makes the fossils stand out once dug up.
The ammonites are about 12 to 19 mm across, with ribs on every whorl. A 25 mm pendant takes one whole ammonite; a mug wall carries a dozen at different turns.
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 30 min for everything on a current printer at 0.2 mm layers: about 1 h 35 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.
