I know a couple of folks on here have made this one but at the urging of @CTimm I am gonna have a go at making one from 3D printed parts. I am gonna make the clustered booster version (there is also a single engine booster version, but that one looks too much like the R1 that I already made). There are not too many pictures of the real thing out there but here are some.
I mostly worked off of this diagram:
Here is what I have so far -- what do you guys think? 18mm motor in sustainer, 13mm mini engine cluster in rear around a single 24mm mount in center (designed to have BT-5 tubes used in rear to keep weight down). I can easily drop the center booster mount down to a 13mm as well (or 18mm) but it is pretty convenient to launch with a single 24mm in booster in some cases. I have not setup all the motor mounts / retainers yet so could easily setup the 24mm mount so you could screw in dummy plate that would convert between 24mm and 13mm. 47.5cm (almost 19”) long and 16.3cm wide
