Well on your way. A few details on the charge wells to help you along.
- The minimum wall thickness was 2 mm (you may get away with less, but I know that works for repeated use.
- I just snaked the wires over the top of the well in this case. Since it was a higher-ish alt flight I wanted to ignite the powder from the top instead of the bottom.
- Tape doesn't stick very well to PETG, so be careful when taping in your charges. A notable exception to the lack of stick is the aluminized tape for HVAC stuff.
Got it! Thanks for the heads-up on the tape. Was the HVAC stuff what you used?
