 To be compatible with standard bricks, the following print settings are strongly advised
 
-- Nozzle: **0.4**, this is equivalent to 1 LDU.
-- Layer height: **0.2**, less than that is barely better and just causes more problems than it solves.
-  If you want to go lower, it's advisable to use heights that satisfy `0.4 % h == 0` such as 0.1.
-  - **Make sure your initial layer height is either 0.2 or 0.4!**
-- Supports: **none**, unless you use the classic option
-- **Make sure you have your flow and z offset calibrated perfectly.**
-  These parts have very small tolerances, it is absolutely vital you have this right
-  or you will end up with parts that have insufficient or too high clamping force.
