Hi, you can use a negative horizontal expansion on cura or a negative size compensation on PrusaSlicer to make the walls thinner, something like -0,5 or -0.3 should do the trick, make sure its printed the way you want to on preview.

Another solution is to do the 3d model again with the lines thinner with experimental settings, giving a negative “Thicken interior feature”

Also make sure you have only 1 blade activated with something like 0,5mm

A third solution would be making the lines in the picture thinner with something like Adobe Photoshop using the maximum filter

Great points! Just consider the Cura method will make everything thinner, including the blade- which may not be desirable. On the other hand, the negative interior features in Cookiecad will leave the blade the right thickness and just make the interior details thinner.

Another way to make the interior lines thinner in the image is using the free windows program getpaint.net. You select the part you want thinner, than click effects → selection → outline selection and outline it in white.
