Non-Planar Spiral Slicer

Every tool here works on the current model, and its result becomes the new current model. That way you can add a flange, split the vase and slice it without saving any files in between.

Stacking Flange

The top edge steps inward at an angle and then rises as a short spigot, which the next part sits over.

Vase Splitter

This cuts the model into wedges, with a join flange on both cut edges. Change any setting to see the cut planes, and drag Rotation to move them where you want them.

This prints flat parts, one layer or several. The outer wall goes all the way round the outside edge as one unbroken line, so the edge stays strong. Inside it, more walls follow the outline and every hole. Where a gap is too thin for a normal line, the nozzle rises as the gap narrows, which lays down a narrower line that fits into it (gap fill).

Parts on the bed

To print several parts in one go, add them here. Click a part, in this list or in the 3D view, to select it. Model transform then moves, turns and scales that part, and you can drag it around the bed. Every part is laid flat when it is added.

Calibrate (once for each printer and filament)

Print the calibration line, measure how wide the bead is near each end, and enter both widths below. They are saved with the printer preset.
