LEGO human optimized for Makergear M3

thingiverse

I printed the original Lego Mini Figure by ustkl and discovered that due to differences in printers and materials, some holes or bosses didn't fit LEGO's size tightly. To address this issue, I imported the original STL into Fusion 360 and made modifications: I thickened the neck, increased the thickness of the boss at the hip-legs joint, enlarged the boss at the hip-upper body joint, and reduced the hole in the sole of the foot. After these adjustments, printing with Makergear M3 (which is nearly identical to M2 v4) resulted in a perfect fit with LEGOs.
