A Board to organize all your Nozzles in one place. It has the threads for the nozzles designed to print. But you may althogh need a bit of torque to screw them in.
The Board is available in two versions. One with the knobs for the stand and one without, to simply lay it down.
If you want to make own stands/holdings for it, feel free. I uploaded the .step file for the normal version.
The Version without th Knobs doesn´t need supports. The version with the knobs and the stand need support.
