I was not able to print the walls parts on my Prusa MK3S+. The original author, PurchenZuPoden was so nice that he has included the STP files, so after few minutes in CATIA the walls separation was done.
No need to glue all the parts together, as the original autor's design has interlocking white edges. The walls are separated with 45degrees cuts - so after you add the white edges, they should be invisible. I have separated the water reservoir parts, that you will be able to print that wall the same way, as the others.
I have printed the walls from ECO MB rPETG Scarlet Red.

Thanks PurchenZuPoden for project and files!
For the printers - happy printing and for the birds - enjoy :)
