[Adding custom nozzles to Cura]

Hi

How is it possible to add custom nozzles to cura? I need 0.2, 0.15, 0.1 mm and can not find presets for it.

Thanks in advance.

[Setting minimal size of suport]

Hi.

 

How can I limit minimal size of support structure to avoid generatind supports in limited spaces? For example, can I limit size of support 3 mm width or length, if I need avoid priting support in narrow space of 2 mm? I need it to avoid printing narrow unstable support structure inside of my model.

I have found "Minimum support Area" in Support settings, but it is not exactly, what I need. 

 

Thank you for your support :)
