A 6, 8, 10 and 12 mm graduated ladder on one tray; single trays for 6, 8, 10, 12, 14, 16, 18 and 20 mm rounds; an 11 mm topper ball; a 2 mm micro strip that rolls ten beads at once.
8, 10, 12 and 14 mm bicones; 6 x 12, 8 x 16 and 10 x 20 mm olives; 8 x 10 and 10 x 12 mm barrels; teardrop, oval, egg and rondelle; three short tubes and seven long tubes.
15 and 22 mm Christmas trees plus a matching 15 mm pair tray, 50 and 32 mm chess pawns and 14 and 20 mm mushrooms.
Every cap carries a recessed lid disc for its clay, every base a log notch with cut-length ticks, and most trays a pin path for piloting the hole.
One 3D printing guide covering every family, the part lists, 1:1 sizing cards and the licence. The supplied 3MF files are arranged layouts with notes, not validated 3D printer process profiles.
Maker workflow
Press a 2.5 mm slab onto the recessed disc in the cap lid and cut the circle, or roll the stated log and cut it at the tick on the base ruler. Each roller also gives an estimated weight in grams.
Turn the cap over front edge to back. On the shape trays the size labels on the base and cap line up at the same end when it is the right way round.
Rest your off hand on the base ledge and slide the cap in line with your forearm with light pressure, one direction, the full tray length. Lift the cap and quarter-turn the bead between sets. The pawn and mushroom are pressed, then finished with short strokes.
Chill the bead, set it back in its trough and twist a pin along the pin path. Remove the bead from the 3D-printed tool and bake it on an oven-safe metal skewer or tray, following the clay brand guidance.
Before you start
Keep the making setup practical
Test the measured portion with scrap clay before making a batch.
Use light pressure and stop if the slide binds.
Remove clay after use with a soft brush or cloth, wipe clean and dry. Do not heat the 3D-printed tool or store clay in a trough.
3D printing setup
0.4 mm nozzle; PETG preferred, PLA also supported. 3D print both trays flat with troughs facing up and the cap lid on the bed. Use 0.28 mm body layers with 0.08 mm layers over the troughs, a 0.20 mm first layer, 3 walls, 1.0 mm top and bottom, 10 to 15 percent gyroid or lightning infill, and supports off.
Confirm the troughs stay open in slicer preview. 3D print one pair first and check that the cap slides freely before using clay. The cap fit is 0.30 mm per side, a free slide rather than a snap.
The library and its final operation evidence remain under review. Preview renders do not establish physical performance.
Before you 3D print
No. This is a preview of digital STL files and a guide. You will need to arrange 3D printing and supply the making materials.
No. Each roller family is its own ZIP, so you can download and 3D print only the beads you make.
The rollers shape solid beads. Most trays have a pin path: set the chilled bead back in its trough, close the cap and twist a straight pin along it. Each family's section of the guide gives the pin length and thickness.
The canonical Maker Licence allows sale of finished polymer clay pieces and excludes resale or sharing of the files and 3D-printed tools. A future eligible Print & Sell member delivery uses its own Member Licence. This preview does not grant access or resale rights.
