LESS GUESSING. BETTER FITTING.
Change one thing. Test again.
Diagnose a cup wrap that is too small, too tall, wrinkled or uneven at the seam with a simple paper-fit checklist.
01
Too small or too large everywhere
Check the printed 50 mm ruler first. If it measures something else, fix the print scale before editing the cup measurements. If the ruler is correct, confirm the unit and diameter/circumference mode. Entering a diameter as a circumference makes the template much smaller.
02
The top fits, but the bottom does not
Remeasure both printable boundaries. A generic 20 oz or 600 ml file cannot establish your cup shape. Confirm that you did not swap the measurements. Wider-bottom cups are supported; the TOP label always refers to the boundary entered as top.
03
The height is wrong
Check whether you measured vertically or along the sidewall, and select the matching mode. The paper should end at the chosen boundaries, not at the cup lip or rounded base. Do not include the lid or non-printable shoulder in the height.
04
The seam overlaps or leaves a gap
Start with an edge-to-edge seam. For overlap or a deliberate gap, the entered amount is measured along the top boundary; its bottom length changes in proportion to the bottom diameter. Coverage also creates an uncovered region. Reset seam settings before diagnosing the basic geometry.
05
The paper wrinkles or lifts
Do not stretch the paper to force it into place. Look for a bulging wall, changing slope, step or rounded section inside your chosen region. This model assumes one ideal circular cone frustum or cylinder. If the cup does not match that model, use a smaller straight-sided region or obtain a supplier-specific template.
