**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.

## Notes

- Base and wall: the column hangs from two spool hangers on the power cylinder; the burner shroud and torch stand use the sealed generator's hole pattern.
