Hey there,

My son has a collection of small Siku toy tractors, but their plastic attachments often break easily. That's why I decided to recreate them using Fusion 360. The replacement front-loader pieces click together securely, utilizing the layer lines as tiny hooks. Disassembly requires a bit of force.

However, the small nibble used to attach to the tractor is quite delicate and tends to break first - my son managed to break the first two test prints! I intend to redesign them to enhance durability.

While PLA is already sturdy, PETG might offer even better durability.

Enjoy the project!
