Parts:

  • the Heatset_Practice coupon and its seven inserts · already on the bench
  • soldering iron · tool
  • flat cold tool, for the last 10 % · tool

Do:

  1. Push each insert 90 % in with the iron, then press the last 10 % home with a flat cold tool.
  2. Check squareness by eye from two directions.
  3. Nudge a tilted insert briefly with the iron.

Check

Seven inserts flush to ≤ 0.2 mm proud, square, with no boss bulged more than 0.2 mm.

What you're looking at

The seven inserts you just set, one per pocket of the practice coupon. A good one is flush with the surface, square to it, and has not made the plastic boss around it swell. A swollen boss will not fit its neighbour.

Caution

A bulged boss is a technique fault, too hot or pushed too fast, never a slicer fault. On a real part with a free-standing boss, caliper the boss OD before and after; on the coupon the raised ring is the tell. src · print plan §1.4
