Description

The hole for the momentary switch is 7mm in diameter. Modify or drill out to accommodate for larger/smaller switch you may purchase.
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.

- one 9v battery
