Nắp và vòng retainer động cơ 29mm cho model rocket

This is the 29mm model rocket motor retainer that I designed for the Extreme series rockets.  I have flown several rockets dozens of times with these using both PLA and PETG.  They are straightforward to assemble and removes the need for unsightly engine clips.  Best of all, if you fry through one of the caps, you can simply print another.

I love them and I think you will too.

If you print and use these, please consider creating a make and leaving a comment.  Also, please like this model if you find is useful.  It really helps me.
