Model Rocket Ignition Box
thingiverse
This launch ignition box is for model rockets. It prints assembled and in place with no supports. For use with one 9v battery. The case has a freely moving switch cover to protect from accidental discharge. The case has a sliding panel to ease access and change out the battery. You will need a 9v battery, momentary switch (normally open), 9v battery clip, and a length of bell wire (or similar). The hole for the momentary switch is 7mm in diameter. Modify or drill out to accommodate for larger/smaller switch you may purchase. All parts, except the battery, should run you less than a couple dollars. Instructions Print with 0.3mm thickness or less. I used 0.3mm and it printed fine. Print with an infill between 15% and 25%. The slide cover location of the main file has integrated supports so remove them prior to installing the slide cover. Installing the switch is a little tricky, but be sure to wire everything first. ALWAYS LAUNCH MODEL ROCKETS IN A SAFE AND OPEN AREA. HAVE FUN.
