Very nice model, as strong as advertised, disturbingly powerful action :-)
.. now I need to buy some nuts to crush with it.
I did the thread and handle in ordinary constructors PLA, and the body in translucent smoky PETG since I have some, and it;s layer adhesion is great. It's also deliberately underextruded (94% of the equivalent PLA setting) which greatly reduces blobbing and stringing. The weird banding you see is the solid internal layers affecting the perimeters a bit as a result; but it is actually warm and nice looking when handled.
Done in 0.25 layers with a 0.8 nozzle, I only used 2 perimeters and 15% infill, this nozzle guzzles filament but makes strong stuff by default on relatively conservative settings.
PS: candle wax on the thread made the action smoother; but it was pretty good by default, the clearances in this model were spot on, everything fitted despite my lazy slicing and printing.
