The items below are included in the download. Styled examples and props shown in the images are not included unless the list says otherwise.
Matching roller parts
One shared base and cap with two identical tree channels.
Portion references
Recessed lid gauges, batch-log notch and ruler, plus a 3D-printable sizing card.
Guide and file list
Complete making and 3D printing guide, part list and licence. The supplied 3MF is an arranged geometry layout with archive notes, not a validated 3D printer process profile.
Maker workflow
How to use the set
Measure the clay
For each 15 mm tree, cut a 15.3 mm disc from a 2.5 mm slab, or cut a 10 mm clay log to 5.9 mm. Repeat for the second tree. About 0.60 g per tree is an estimate, not a guaranteed weight.
Align the cap
Flip the cap front edge to back so the deep parts of its trough match those in the base. The symmetric rails also accept the reversed orientation, so check before pressing.
Form the piece
Pre-form two cones with pinched tails. Place one in each trough with both trunks toward the trunk ends. Use one-direction strokes along the tray and quarter-turn each tree between sets. Let the trees rest or chill before lifting their fine edges.
Finish separately
Choose matching findings or pilot each tree along its axis while the cap is flush. Use a straight pin at least 40 mm long and no more than 1.0 mm thick, entering from the tray end nearer that tree. Twist gently. The roller shapes solid trees; it does not make a hole by itself. Remove clay from the 3D-printed tool before baking and follow the clay brand guidance.

Before you start
Prepare your 3D print and clay
What you need
3D printer or 3D printing service with a 0.4 mm nozzle
PETG or PLA filament
Conditioned polymer clay
Four self-adhesive TPU or silicone feet per base
Straight pin at least 40 mm long and up to 1.0 mm thick, plus chosen findings
Oven-safe baking surface and clay-brand baking instructions
Not included
Physical 3D-printed tools, clay or filament
Pins, sticks, findings or self-adhesive feet
ready to 3D print process profiles, fit coupons or separate piercing guides
Keep the making setup practical
Making tips
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.
3D printing setup
How to 3D print it
Start with one test model at 100 percent scale, then check fit and finish before 3D printing the complete set.
Print settings and orientation
Recipe to set yourself
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 adaptive layers to 0.08 mm or finer 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.
Inspect the slice and fit
Confirm the troughs remain open in slicer preview. 3D print one matching assembly first and check free sliding before using clay. The intended side clearance is 0.30 mm per side; this is not a snap fit.
Current preparation status
The current 3D print recipe and final operation evidence remain under review. Preview renders do not establish physical performance.
Before you 3D print
Questions makers usually ask
Are finished tools or beads shipped?
No. This is a preview of digital STL files and a guide. You will need to arrange 3D printing and supply the making materials.
Does the roller make the holes?
Choose matching findings or pilot each tree along its axis while the cap is flush. Use a straight pin at least 40 mm long and no more than 1.0 mm thick, entering from the tray end nearer that tree. Twist gently. The roller shapes solid trees; it does not make a hole by itself.
Can I sell what I make?
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.
Where will the guide and support information be?
The completed download will include the full guide, file list and applicable licence. Use the support route supplied with the delivery you actually receive. This preview offers no download or checkout.
