I've adapted this model:

Using Meshmixer and a reasonable amount of patience (lol).
The design was meant to be printed using the MMU2S from Prusa Research.
High resolution is recommended for quality results.
I recommend printing the Bowtie individually and super-glue later
Add all model files together at the Slicer and address each model part desired filament.
(not 100% tested yet, but I've printed the original model once at high resolution and the results were pretty nice. I upload photos of the multi material version one as soon as I print it).
