Robot mini pendant with kicking legs

I accidentally saw a small wooden doll with kicking feet, and its short legs swinging looked especially cute! The advantage of having a 3D printer is that if you like it, you can make it yourself. After testing, the effect was good, so I'm sharing it with everyone. Those who like it can download and print it directly.

This is the third variant of the previous model, the pendant version. It's convenient to hang on a bag. When walking, the doll's feet will swing more and look better.

Printing and Assembly Details
1. **Hand Assembly**: No additional accessories are needed; simply insert a piece of φ1.75mm filament ≤4 cm long.
2. **Eye Treatment**: When printing, you need to change to white material once (manual change is possible without AMS); finally, you can color the pupils black with a pen.Alternatively, you can just print it and then color it with a marker pen for equally good results.
3. **Leg Spring Selection**: The model file includes a printed spring, but after testing, the effect was too stiff (the legs would kick very high). It is more recommended to use extension springs, which are low-cost and effective.
- Specifications 0.3*3 (wire diameter 0.3mm, outer diameter 3mm): Softer hardness, gentler rebound.
- Specifications 0.4*3 (wire diameter 0.4mm, outer diameter 3mm): Initially stiffer, softens after slight stretching, more adaptable.
- Purchase Recommendation: Both specifications are 2 yuan for 1 meter with free shipping. 1 meter can make several. Adjust the length as needed when cutting, and be careful as the cut ends can be sharp to avoid scratches.

You can also buy fixed-length ones with hanging loops. Search for 'extension spring' on major platforms. Any extension spring with an outer diameter of 3mm will work.
4. **Shoe Printing**: 100% infill is recommended. Although it uses slightly more than 1 gram of material compared to 15% infill, the increased weight makes the kicking effect more pronounced.

Printing Settings and Precautions
- Basic Settings: The 3mf file has all adjustment parameters preset; you can print directly.
- Key Parameter Modification: When printing spring components, the preset 0.5 in the printer process profile needs to be changed to 0.45, otherwise printing will fail.
- wall Generator Mode: Be sure to use 'Classic Mode'; Arachne mode will reduce spring elasticity, and the joints are extremely prone to breakage, so it is not recommended.
