Bánh xe thay thế cho tàu Duplo

The original Duplo railway wagons (such as the ones from the number train set) do not fit on all train track pieces, especially the bridge and switches, because its wheels are to wide.

This replacement wheel makes it compatible with all these track pieces.

Remove the original wheels by pressing in two opposing wedge-shaped objects. I do recommend this removal tool: https://www.thingiverse.com/thing:4935672

Printing tips:

• layer height 0.15–0.2 mm
• 3 perimeters
• 4+ top and bottom layers
• support required
  • if your printer supports multi-material printing, I'd recommend to use a snug support with a different/soluble material.
