I was updating my Ultimaker2 with the 3dSolex Olsson Block and thought i was in need for a Nozzle holder for the hundrets of Nozzles i would change in the furture. I was not able to find a nice holder which is having place for the wrench and enough place for the nozzles so i was drawing this holder. The red marker pin you can put in where your actual nozzle comes from.
Markierung_aktuelle_Spitze_V1.stl ... is the making pin
Spitzenhalter_V1.stl ... is the holder
Nozzle 0,25 for a nice finish arround the text. it took about 12houres.
