We did not like the little plastic bags with all the nozzles inside. So we decided to design a holder, following the "5S" methodology as best as possible. https://en.wikipedia.org/wiki/5S_%28methodology%29 Because the thread on our nozzles is a standard M6 thread we decided to insert M6 Nuts inside of our PET printed Part. By doing so, we think, that we can screw in the hot nozzle fresh of the printer without damaging your holder.We wanted the holder to look like a thermometer from afar. To achieve that we made the scale stick out to the left side. Unfortunately PET is quite a bitch when it comes to retraction and string pulling, even the application of a hot air gun did not resolve the crappy look of our scale. So we just printed the scale in PLA and glued it to the side of our holder.
