I printed the 3.0 Nm one in white PETG and used the Torque Measuring Lever (https://www.thingiverse.com/thing:2670493) and got about 1200-1300 g on my kitchen scale (with a range 0-5000 g) so if I got it right that corresponds to 2.4-2.6 Nm max torque measured before skipping.
I'm going to use this to change my E3D V6 nozzle (for the first time) on my Prusa i3 MK3. I guess that should do it pretty well.
Clas Ohlson PETG
- Nozzle diameter: 0.4 mm
- Layer height: 0.2 mm
- Perimeters: 8
- Solid top layers: 6
- Solid bottom layers: 4
- Infill: 80% rectilinear
- Extrusion width: 0.42 mm (infill 0.5 mm)
- Infill/perimeters overlap: 25%
There was almost no actual infill in the tool due to perimeters making the parts almost 100% solid.
