The Batman Model is great, but needs a Superman Companion.
So I reused the compatible parts and colored them accordingly.
From the remixed Batman I used:
From the remixed Superman Model I used:
I combined the Body + Logo + Abs + Belt to a single object, colored it in Bambu Studio, and printed it with MultiColor, you could also print it as single parts and glue it.
The same for the legs – added a modifier at some height to change from red to blue, works nicely for multicolor printers, but is doable manually as well as it is a single filament change.
I added the whole Bambu Studio 3mf file, am not sure if other slicers can open that, but you can use that to check the settings or to print it from bambu studio with your printer (if not a bambu lab printer).
The author remixed this model.
Used the Batman model, changed the colors a bit and scaled the Hair, Face and Superman Logo part accordingly, combined the Body with the Logo, the abs and the belt.
