EXTRACTED KNOWLEDGE / HOW-TO FROM CONVERSATION

QUESTION / CONTEXT: Im trying to fix my toilet handle using my 3d printer what is a good connection I can use for the handle to the chain arm

  1. Make your handle’s inner shaft a D-shape (flat on one side).
  2. Print the arm with a matching D-bore and a slit down one side.
  3. Add two M3 or 6-32 cap screws across a clamping bridge to pinch the slit shut.
  4. Pros: Very strong, no wiggle, easy to clock the angle before tightening.
  5. *Dims to try (tweak to fit):
  6. Typical tank lever shaft: 3/8" (~9.5 mm) square or round. For a D-shaft, make Ø9.5 with a 2.5–3 mm flat.
  7. D-bore: model at +0.2 mm clearance.
  8. Clamp bridge thickness: 3.5–4 mm; screw holes Ø3.2 mm for M3 or Ø3.5 mm for 6.
