Description

A side-entry split compression fitting for 8 mm round rod. It clamps at any point along the rod without sliding over the end: load the rod through the 9 mm side slots in the housing and nut, then turn the nut about 180° so its slot sits over solid housing wall. It is not a hose clamp, ring clamp, C-clamp, or ordinary threaded connector; the split collet is driven into the cone and closes around the whole circumference of the rod.

Fit and assembly

  • Rod size: 8 mm; collet bore: 8.4 mm.
  • Parts: housing, split collet, compression nut. Print as three separate pieces.
  • Housing: 22 × 2 mm external thread, 26 mm collar, internal cone from 15.6 mm to 11.8 mm, 9.2 mm bore.
  • Collet: one full-length slot plus staggered slots so it closes evenly.
  • Nut: hex body with an end wall that pushes the collet into the cone; 0.2 mm thread clearance for FDM.
  • Printing: lay the parts out flat and lift the stack so the nut rests on the plate.
