These are programmatically generated G-code files for 3D printing walking slinkies. Two sizes are currently available for testing:

• 24 mm diameter slinky, 60mm height (190C_50FAN_9R1_12R2_60mm_PLA.gcode)
• 24 mm diameter slinky, 100mm height (190C_50FAN_9R1_12R2_100mm_PLA.gcode)
• 60 mm diameter slinky, 40mm height (190C_50FAN_26R1_30R2_40.0mm_PLA.gcode)
• 60 mm diameter slinky, 80mm height (190C_50FAN_26R1_30R2_80mm_PLA.gcode)

More versions will be shared once these are tested and confirmed by the community.

🌀 This is a programmatically generated G-code for printing a working 3D-printed slinky. There is no STL file, as the model is generated directly via Python script based on printer and filament parameters.

✅ This G-code has been successfully tested on:

• BambuLab A1
• BambuLab A1 mini
• BambuLab X1C (tip: change temperature to 170°C after first layer for better result)
• Prusa MK3
• Prusa MK4
• PWS 400k
• Let me know in the comments if you print it on another printer!

using basic PLA (avoid silk, glow, or textured variants).

It should work on many other printers too, but please use with caution and monitor the first layers closely.

🛠 If filament isn't extruding properly, raise the temperature manually during the print.
🧊 If the model warps or layers fuse too much, try reducing the temperature.

After printing, the layers should separate easily using a sharp knife. If they’re hard to split or feel fused together, it’s a sign the print temperature was too high and the layers over-bonded. Try lowering the temperature slightly when printing.

💡 This G-code is part of a larger experimental project exploring how far 3D-printed motion and mechanics can go, shared as a way to learn, tinker, and fail publicly.

If you test the print, I’d love to see your results! Share your experience in comments please!
