This is INTEGZA'S micro pulsejet rocket I well... copied using tinkercad and it was a nightmare I'm newer to 3d modeling
so yeah it took like 3 hours of pain and suffering so a comment or like really helps me out but here it is I hope you like it.
and if you want me to redesign it in any way just leave a comment! Oh and if you need to know how to use it then watch INTEGZA'S pulsejet engine video.
