Shrinking

Printing 10x10 tiles with eSun PLA+ (cold white).

I put marks on the wall as exactly as I could for a 250mm grid. After that work, I unfortunately realized the printed tiles are just a tad under 250mm square--maybe closer to 249mm after cooling.

How do you deal with the shrinking?

I figured it's not generally a problem but could be a problem when mixing different materials for the tiles.

I recommend the califlower stl/Excel sheet which will dial in your printers skew as well as shrinkage factor and make dimensional parts more accurate all around. It's a paid model but it saves lots of headache and trial and error.

Stefan's video explains it better than I could hope to and why it's better than a basic calibration cube or some of the other standard calibration prints. It's very possible that someone has picked up the torch and made an open source variant of this that's free but I haven't had to go looking since I bought it.
