Hi I want to print a downscaled object(from several meters to 2% of original size). It has a lot of pipes and pumps and small objects that are downscaled too. Is there a way to print a downscaled pipe (imagine a can) as a full modell or with several mm wall thickness to the inside in Cura that it get's stable? And is there a way to upscale small objects somehow or to thicken up to a minimum wall size? I tried several settings in Cura with the housing but didn't had success in it.. Best & thanks for your help Simon
