After trying some models from makerworld, I was so unsatisfied about the accuracy of the printed models, sometimes too large, or too thin…

I spent hours to model in 0.001mm precision the perfect model for that brick.

You will be satisfied to notice that this brick will perfectly match either on the top or under fix.

I will publish soon some other models with the same precision.

WARNING : Print that model with 0.2mm nozzle only, if you print with 0.4mm the little circles will print wrong and mess the entire project.
