Estes Rocket Igniter Clip Spacer

thingiverse

This is very basic but its also very effective. This is a spacer to help keep your alligator clips from touching when launching a model rocket with an Estes style igniter. You simply slide the igniter leads through the holes and the spacer helps prevent the clips from touching. The walls are ~1.8mm thick, so they aren't going to add much weight causing the entire ignitor to pull the plug out of the motor. I went through making guides to attach to the clips themselves but this ended up being the easiest and most effective method that i've come up with. 2 versions, a short (like in the images above) and a longer version. I printed these flat on the build plate and no supports needed.
