Super simplified IM-1 scaled to fit inside the 1:96 Falcon 9 model, using the same couplings as for Starlink and Dragon payloads associated with that model (see Thingiverse https://www.thingiverse.com/thing:4503875 )

Note this is only the IM1 payload - you have to print the Falcon 9 fairings, 1st and second stages, and all the required couplings yourself! But it is an awesome project!
