Tolerance test

Understanding the tolerance
It's an additional gap left while designing in order to make moving parts move freely and as smooth as possible without being too loose at the same time, like holes, screws, connectors… It has to be considered as well for fitting objects into others (male → female).

Application
Let's say you want to slide a 10 mm cube (male) into another one, the amount of tolerance is applied once per side. That means if you leave 0.25 mm, it will be a total of 0.5 mm for each XY axis. The female cube will then measure 10.5 mm (horizontally).

The object
This print is a good to go for testing your machine's limits when you have parts that move or sliding pieces. The amount of tolerance is indicated on front and back. Divide the corresponding number by 100 to get millimeters.

Notes
Slicers have an option to compensate for material shrinkage so you'll probably want to play with this setting to adjust your print profiles instead of touching the steps/mm. Unfortunately, there is no slicer which has independant X-Y shrinkage compensation setting to my knowledge, only mixed setting as “horizontal shrinkage compensation” for example.
