For some time when using my head knives I have wanted a stand up holster/stand to put it in safely between the repetitive using of them. Its a long print job but for me it is worth it at least. Here is the stl file - HEAD KNIFE HOLDER.stl
You will need to lay it as shown in the below pictures. To try and save print time I have drawn it with a hole in the base to act as a support. This way in Curra I have given it No fill. Here is an extract of the settings I used.
