Exact dimensions. Every file is drawn at true size with no printing tolerance. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your printer's or process's clearance before making the part. Mating features

sizes: 3 in table

Notes

Two halves that clamp the hot spool's tube with their lids (2 × M4 × 20) just above the fins and hang round them, open at the bottom: the torch or burner below fires up into it, the gas leaves through six windows under the lid.
It touches only the tube at the lid. The heat source is the builder's choice: a propane or butane torch head in the torch stand, or a small gas burner firing into the open bottom.
