Hi all, I find ALL my hole dimension are approx. 0.3mm smaller than the cad stl file. I printed 3, 5, 10, 20, 30, 40, 50 in ABS and PETG I used CURA 3.2.1 for my print and both materials had the same results for the holes, the outside dimension on the PETG was nearer to the stl cad size. If I use the scale option in Cura it just scales the outside and NOT the hole dimensions. Is there a plugin to fix this or have I to just increase Hole diameters to compensate, which is OK if I am to print my own design/drawn models. Awkward if I have to pass on information to 3rd parties about how they should adjust their hole sizes. Thanks for any ideas. hole size check.stl
