Threads
From the library
ISO threads that run out cleanly at both ends, bolts, nuts, knurls and gears — parametric, regenerated without the plugin.
Use case · Makers & 3D printing
Parts that fit on the first print.
A PLA box, Ø56 × 70 mm, with a screw-on cap: threads and knurls from the parts library, the 0.3 mm clearance a named parameter, and the overhangs, the wall thickness and the printer's build volume held by requirements the model checks on every change.
Fit
Clearance as a parameter
Name it once, use it in every dimension, change it after a test print.
Check
Requirements in plain words
"No overhang beyond 45°", "fits a 180 mm build volume" — checked on every rebuild, with what fails and where.
Weigh
Mass from the material
Volume, mass and centre of mass from the material's density — before you slice.
Out
STL and 3MF
Meshes for any slicer, with the bodies' names and colours in 3MF.
Agent
A 3D-printing skill
The assistant ships with a skill for printable design: overhangs, wall thickness and tolerances.

Import a STEP file, push a face, put a dimension on it. 5 days, every tool, nothing to pay until you decide.
