Inkscape extension that generates paper model of an extruded shape
Given a closed path of straight lines, this program generates a paper model of (1) another copy of the closed path; (2) an extrusion (or more if it exceeds the maximum length) represented by a strip with tabs and score lines; and (3) strips for covering the tabbed strips. See the file How_to_use_extruder.pdf for details. Inkscape 1.1 Papercraft Extruder Extension from Installation to Design Space is a video tutorial on using the extension.
