BR-7 Multi-Stage Rocket

This is my 7th series of model rockets powered by Estes motors. Other then the 35 mm diameter it is a complete redesign of the BR-5. Does not require any parts be glued together, uses screw adapters to screw together, allowing for easy disassembly and reloading of rockets.

I provide both the origional Rhino 3D modeler file, the .3mf file I use to generate .gcode, the .gcode for my Creality Ender 3 Printer and .stl for thingiverse because it does not like the other file formats. With the .3mf files I set different printer settings for sub-components in each part. I do not recommend print each part at the same setting and infill as this will likely result in the rocket being too heavy.

I design it to carry up to 3 SQ-11 cameras, these ~24 mm wide cube shaped cameras cost just $10~$15 (Jan '20) off the internet and turn out to be reasonable tough.
