Cadjitsu 1.4 makes threads you can print and use: pick any hole or post, choose a size, and get a real helical thread that runs right through, fitted to that size on its own axis, with a countersink for the screw to start on. It adds the extra-fine UNEF series (1/2-28 and friends) and a new front page with screenshots.

Downloads

File For
Cadjitsu-1.4.0-macOS.dmg macOS 15 (Sequoia) or later on Apple Silicon
Cadjitsu-1.4.0-Linux-x86_64.tar.gz 64-bit Linux with X11 and OpenGL

macOS:

  1. Open the dmg and drag Cadjitsu onto Applications.
  2. The app is ad-hoc signed, so clear the quarantine flag once:
    xattr -dr com.apple.quarantine /Applications/Cadjitsu.app
  3. Open Cadjitsu.

Linux:

  1. Unpack it: tar xzf Cadjitsu-1.4.0-Linux-x86_64.tar.gz
  2. Run Cadjitsu-1.4.0-Linux-x86_64/cadjitsu.

It brings its own Qt and OpenCASCADE; the system only provides X11 and OpenGL. On Debian or Ubuntu, if something is missing: sudo apt install libgl1 libegl1 libxkbcommon-x11-0 libxcb-cursor0.

What's new in 1.4

Threads that print and fit

  • Any hole or post, any size. Pick a hole's wall or a post and a size: the cylinder is first fitted to the thread on its own axis. A hole too big is filled and bored again, one too small opened; a post too thin is grown out, one too fat turned down. The panel says what will happen ("A 12.70 mm hole, filled and bored to 1/2-28 UNEF").
  • Always modelled. Every thread is a real helical ISO profile with print clearance (0.15 mm by default). It runs right out through open faces; at a blind bottom or a shoulder it fades out to the root. A post's tip gets a 45° chamfer.
  • Countersinks. A threaded hole gets a countersink so a screw starts true: on the Top (the face drilled into, by default), the Bottom or Both, with the included Angle (90° metric, 82° inch, 100°, 120°) and the Diameter at the face (blank: a little over the thread). The same options are on Hole > Tapped.
  • Recent sizes first. The five thread sizes you used last head the size lists, in the Thread tool and in Hole > Tapped.
  • Never held up. A long thread is computed in the background and abandoned the moment you pick something else; while a preview takes a while, the panel says Computing the preview… and the hole lights up in yellow.

More sizes

  • UNEF extra fine, #12 to 7/8" (1/2-28, 3/4-20…), and the in-between UNC and UNF sizes (#2, #5, #12, 9/16", 7/8").

AI agents (MCP)

  • thread: countersink, countersink_ends, countersink_angle, countersink_diameter; any hole or post takes any size.
  • Tapped hole: thread_countersink, thread_countersink_ends, thread_countersink_angle, thread_countersink_diameter.

Front page

  • The README is now a landing page with pictures of what Cadjitsu makes, all built through the MCP tools by the showcase self test (scripts/readme_images.sh renders them again).

Changed

  • The Thread Type choice is gone: threads are always modelled (mode and thread_mode are ignored over MCP). Designs that left small threads as a tap drill now get the thread.
  • Countersinks go on the top end by default, not both ends.
