One of the reasons that I got into 3D printing initially was to create a COG that was no longer available to purchase. Initially, I tried to find a commercial business to do it for me, but alas no luck. The upside was that I decided to get into the 3D printing world, which has been great.
However, my attempts to create a COG that I am happy with still seem to elude me. I’ve gotten close using PLA:
but I wanted to make it out of Nylon so it was more heat resistant but have had challenges doing that.
Currently, I am using red PETG and have managed to get my version 5 to print with the 0.2mm head::
but the shaft is all wrong and doesn’t have the definition for the screw fitting.
What I tend to get a lot when I’ve been testing is results like this that I got with version 4:
Now I’m not quite sure why the same basic model ends up with these vastly two different results?? I also would have thought that the finer nozzle (0.2mm vs 0.4mm) would have made the definition of the screw in the shaft better, but apparently not.
My aim here is mainly to have a base model (COG) and see what different materials and settings, like the nozzle make.
