Mini rack I designed (aside from the Pi mounts). I have a Bambu A1 mini so everything was made with the intention of being able to print it on that. I got 2 36" pieces of angle aluminum and cut them in half to use as rails. All of the holes are sized for M6, aside from the screws that hold the fans and I just used the screws that came with the Noctua fans.
Files include the top and bottom pieces of the rack, a cable tray, and the dual 60mm fan mount.
