How do you handle models that have no clear scale reference? Do you guess the size, or do you use software to measure and resize before printing?
I used to just eyeball the size and hope for the best, which led to some hilariously tiny spaceships and one dragon that was supposed to be menacing but ended up fitting in the palm of my hand. After ruining several rolls of filament, I started bringing unknown models into basic free slicing software to measure them against a real world object like a 50mm cube or a known miniature base. A guide I found on https://www.gambody.com/ explained that many professional designers include a hidden reference plane or a small ruler object in the file itself, and since then I always open the STL in Meshmixer first to check the bounding box dimensions before printing anything. If there is no scale reference at all, I import a simple 20mm calibration cube from my own library, resize the model until it looks proportionate next to that cube, then print a single small test piece at one percent infill just to confirm the fit. Guessing the size has never worked well for me.
