Stands out in the superhive library because it packages the full sliceform pipeline — mesh cleanup, slicing, slotting and pop-up tabs — into four modules inside Blender, producing flat parts arranged for SVG export.
Sliceform Popup Tools (wk_sliceformPopUp) works inside Blender to transform a 3D mesh into a sliceform — a physical model built from intersecting flat slices. The results fold flat like pop-up cards or assemble into large-scale sculptures in paper, wood, cardboard or metal, and the add-on is built to help design laser-cutter-ready models directly in Blender.
The add-on includes four modules. MeshMaker combines multiple objects into one and uses voxel remeshing to close holes and create watertight geometry, with voxel-size control plus Solidify and Displace options for thin or leaky surfaces. SliceMaker defines a slicing grid — slice counts in X and Y plus a boundary offset — and uses boolean operations to cut slice pieces. SlotMaker adds interlocking slots based on your material thickness and can embed slice numbers like x01 or y02. TabMaker builds folding boxes with glue tabs and includes an SVG Arrange Layout tool.
Version 1.5.0 renames the Debug checkbox to Step by Step, which can reverse the boolean cubes so slots flip to help with overhangs. MeshMaker now warns about overly fine voxel settings, and object rotation or scale is applied automatically.
Sliceform Popup Tools is best for makers using laser cutters or plotters, designers and educators prototyping in 3D, and artists creating sculptural sliceforms.
Sliceform Popup Tools is completely free to download and use.
Sliceform Popup Tools is listed as compatible with Blender 5.1, so it targets a current Blender release. It runs as an add-on built around four modules — MeshMaker, SliceMaker, SlotMaker and TabMaker — that handle mesh preparation, slicing, slot creation and pop-up mechanics. For the exact Blender version it supports and any setup notes, check the developer's page before installing, since compatibility can shift as new Blender releases and add-on updates arrive.
Sliceform Popup Tools produces the flat, front-facing objects needed for a clean SVG export, and its integrated SVG Arrange Layout tool flattens and arranges every slice, sorting them alphabetically for easier recognition in vector programs. For the actual SVG file, the developer recommends the free add-on Outline To SVG. Once exported, the parts can be edited in any vector software, and the slice numbers embedded in geometry, like x01 or y02, help you match pieces during reassembly.
Sliceform Popup Tools renamed its Debug checkbox to Step by Step in version 1.5.0. When Step by Step is on, you can reverse the red and blue boolean cubes, which reverses the slots. This helps with overhangs so parts don't fall down. The same Debug-style control also lets you adjust slot geometry manually for complex shapes, which is useful when the automatic slotting needs fine-tuning on trickier models before cutting.
Sliceform Popup Tools is built to design models you can assemble in paper, wood, cardboard or metal, folding them flat like pop-up cards or building them into large-scale sculptures. SlotMaker takes your material thickness — for example 1.5 mm for cardboard — and adds interlocking slots so slices fit together cleanly. That focus makes the add-on aimed at makers using laser cutters or plotters, alongside designers and artists working in physical materials.
Sliceform Popup Tools is listed as free in this catalog. Because licensing and pricing can change over time, check the developer's page for the current terms before you rely on that. The add-on itself bundles all four modules along with the SVG Arrange Layout tool, so the full sliceform workflow from mesh cleanup through slicing, slotting and pop-up tabs sits inside the one add-on, and a demo video is also available.
