There was miscommunication when it comes to the minor details of the print, something related to the proper infill, but Walter's World was very open-minded and willing to offer potential alternatives and solutions without much hesitation. They were elaborate in their responses, which I highly appreciate these days, and were very kind in offering their experience and time into helping decide whether the product would work (with different specs).
They were overall very professional, and if I had to interact with someone for my prints, I would definitely want it to be them.
