Lego Heart Box Stackable

Model of small stackable box  (or not stackable - there are two variants) in shape of heart, which is compatible with Lego like building system.

How to Print?

Similar to what I wrote in the Snowflake model, there are three options:

1. Printing Variant A at 100% (Risky):
   This version is designed exactly according to the dimensions of bricks in systems similar to LEGO. However, it’s highly likely that after printing, the studs will be slightly smaller, causing the bricks to fall off. Every FDM printer operates and prints differently.
2. Printing Variant B at 100% (Recommended):
   This version enlarges only the studs by 1.06x while maintaining the spacing and overall size of the letters at 100%. This is the recommended option, as it works best in my experience.
3. Print a Calibration Test Plate a then scale Variant A:
   Use a calibration test plate to determine the precise scaling factor for your printer that works best with LEGO or similar bricks. However, if the difference is too large, only single bricks (e.g., 1x1 stud, such as LEGO Dots) will fit well, while larger bricks (e.g., 2x1 or 2x2) may not fit due to changes in overall size and stud spacing.
