Shape

Heightmm Body widthmm Neck widthmm Shoulder position%

Maker sizes go up to 240 mm tall and 200 mm wide. Anyone can try them here; saving and printing past the free sizes needs Maker.

Body & shoulder

This starting shape’s body is drawn as a curve. Choose Edit this shape to redraw it, or use height, widths and cross-section to adjust it.

Base edge rounding mm

Neck & lip

Screw caps use a threaded neck, so the lip is set by the thread.

Cross-section

Front-to-back depth%

Corner sharpness%

Shaped bodies blend back to round before the neck, so every closure still fits.

Surface textureMaker

Try any texture in the preview. Saving and printing a textured vessel needs Maker.

Pattern

Textures press outwards, so the wall never gets thinner. They fade out towards the neck and around the front motif, and are shaped to print without supports.

Handles & feetMaker

Try handles and feet in the preview. Saving and printing them needs Maker.

Handles Feet

Handle arms rise at 45°, so they print upright without supports. Feet print as their own file and push into sockets under the base, so the pot still prints flat; spread splays them outwards for a wider, steadier stance. A vessel on feet does not stand in a tray.

Closure

Type

Thread pitch mm Thread turns Fit clearance mm

Fit clearance is the gap between the parts. Raise it if the closure is too tight on your printer.

Closure texture & topMaker

Try a closure texture or top motif in the preview. Saving and printing them needs Maker.

Grip texture Motif on top

The grip band runs round the head of a cork or cap, or the rim of a lid, which is raised to carry it. Top motifs are engraved, because the top prints face-down on the bed.

Front motif

Motif

Style Edges

Sizemm Height on body% Relief depthmm

Sloped edges print on the upright bottle without supports, and the wall follows the motif so it keeps its thickness.

The body, closure and any multicolour or glue-on parts keep their intended 3MF assignments.

Walls & base

The defaults suit a 0.4 mm nozzle. Thicker walls are stronger but hold less.

Safety

Small parts: borderlineThe screw cap is only just larger than the 31.7 mm small-parts test cylinder. Treat it as a choking hazard: not suitable for children under 3 years.
Not for food or drinkPrinted layers trap bacteria, most filaments are not food-contact certified, and printed vessels are not guaranteed watertight. Use for display and pretend play only.
CleaningWipe clean or hand-wash in lukewarm soapy water. Not dishwasher safe: PLA softens at around 55 °C.
Maker responsibilityWhoever prints and supplies this vessel is responsible for how it is made and for meeting local product-safety rules, including toy-safety requirements if it is sold as a toy.
