📝 Print Note – AB Motor Lower Part

⚠ Many users of the previous version had problems here due to incorrect supports.

Do NOT use “Tree Supports” unless you leave a big gap — with just 1–2 layers of support, they don’t work well for this part.

Instead, use Grid Supports (auto-generated) as shown in the preview example.

No extra custom settings are needed — just let the slicer generate grid supports.

✅ This ensures proper bridging around the motor mount holes and avoids weak or messy overhangs.
