A set of "cubes" to tune the extrusion multiplier. Each piece features a number so that you don't need to write it :)

Test "cubes" that feature the numbers from 90 up to 110 that you can use to slice your own extrusion multiplier calibration models for both visual and precise methods
Dimensions & print time
Visual: 20x20x5mm, 10 min to print
Precise: 25x25x25mm, 14 min to print (vase mode, no bottom layers)

Tip of the day
It's practically impossible to achieve both dimensional accuracy and perfectly smooth top layer (without ironing), it's just the nature of FDM printing. If you try to fine tune your extrusion you might easily find out you need (for example) 1.02 multiplier to get perfect wall thickness and dimension, but your top layer will be a bit rough. And with the same filament you can get perfectly smooth top layer with 0.93 multiplier, but your dimensions will be off by 0.04-0.05mm on X&Y axis. And there's really nothing you can do about it. Of course you can try something in the middle to get good dimensions and good top layer. Or you can just make two profiles, one for dimensionally accurate prints and one for perfectly smooth prints (that is my plan, actually).
Good luck!
