You could move your new pulley definition to your own library to avoid modifying NopSCADlib but if you share the definition I could add it to NopSCADlib for you.

Would be great if you could add M4 as I actually use those, so far not on anything I needed to model.

Do we need such large parts in the library? I am struggling to find anybody that sells them. What sizes are you actually using?

Also the biggest screw in the library is M8 at the moment. I think the biggest screws I have ever used anywhere are only M10 as the tensile strength of...

Thanks. I will add them. I will need to change the code because I had assumed GT2 was 2mm pitch but GT3 is also. So the current code would show...

I have added your belts.

I think layer height > width isn't physically possible because the nozzle would be too high to place the filament on the bed, or the layer below. layer_heigth0 is a...

Probably needs an assert() to check extrusion_width >= layer_height. It can never be less when extruding a perimeter. The filament is either squashed to make it wider than it is...

Extrusions are all metric outside the US. E2020 is 20mm by 20mm not 2" by 2". Having a series property makes sense but you would also need a duplicate set...

Rather than a series number it might be better to have say E1010 so the code has a way to find the dimensions of the smaller slots, etc.
