lego compatible bricks love heart

Generated as a test using online Lego generator: https://bricks.lapinoo.net/

You can load and edit the blocks on there by entering the codes:

• HPHPLG
• UYJXWO

After that I just click through to download STL files for baseplate and bricks.

I had to adjust my settings to get this to print nicely:

• Nozzle 0.6mm
• Infill 20%
• No supports
• Layer height 0.35mm/fast
• Raft - 3 layers, 0.1mm z-distance
• Printed in gray PLA

Interesting experiment. This took just under 2 hours to print and about 45 minutes with flush cutters trying to get the raft off so wouldn't recommend printing out entire Lego sets but maybe useful if you've lost a regular brick.

Results are mixed. As Lego blocks they don't really work as something you'd give to a child. The bricks only just stick together which is still quite impressive for an online generator. You can adjust the tolerances when generating the STL but I left everything at defaults. The bigger blocks (2x4, 2x2) also work better and are easier to flush cut then the small skinny blocks (3x1).

The result is a build that just barely hangs together. 6/10
