Make threaded rods and threaded holes that print and screw together, in metric sizes from M3 to M12 or any size you like.
Adding a thread
- Choose Create ▾ › Parts › Threaded Cylinder for a rod, or Threaded Hole for a hole. Both start as M8, 20 mm long.
- A threaded hole cuts like any hole: group it with the solid it goes in. See Solids and Holes.
The Thread section
- Size: M3, M4, M5, M6, M8, M10 or M12 sets the diameter and the pitch together, as ISO coarse threads: M3 0.5 mm, M4 0.7, M5 0.8, M6 1, M8 1.25, M10 1.5 and M12 1.75. It says Custom when they don't match a size.
- Pitch: from one crest to the next, in millimetres.
- Clearance: how much smaller a rod is made, and how much bigger a hole, so printed parts fit. It starts at 0.1 mm, so a printed rod in a printed hole has 0.2 mm of play.
- Direction: Right-hand, which screws in turned clockwise, or Left-hand.
- Starts: 1 to 4 threads side by side, for a faster lead.
- Profile: Metric 60°, or Trapezoidal 30° for lead screws.
↑ and ↓ nudge the pitch and the clearance by 0.05 mm, or 0.25 with ⇧. The diameter and length are in the Size section.
