Print Recommendations
Material: TPU filament
Infill: 7- 8 % recommended for a soft flex feel
Walls: 2–3 walls recommended
Layer height: 0.16 mm works well, lower layer height for smoother detail
Speed: Print TPU slowly for cleaner results, you may need to reduce the speed at the last ¼ for more stability
Bed adhesion: Brim is recommnded, especially for larger sizes
For stronger daily-use slippers, consider increasing infill or wall count depending on the user’s weight and TPU hardness.
Size Guide / Scaling Chart
Base model length: 185 mm = 100% scale
Recommended method:
Measure foot length from heel to longest toe, then add 8–12 mm comfort space.
Use this formula:
Scale % = Target slipper length ÷ 185 × 100
| Foot Length | Suggested Slipper Length | Scale % |
|---|---|---|
| 120 mm | 130 mm | 70% |
| 130 mm | 140 mm | 76% |
| 140 mm | 150 mm | 81% |
| 150 mm | 160 mm | 86% |
| 160 mm | 170 mm | 92% |
| 170 mm | 180 mm | 97% |
| 175 mm | 185 mm | 100% |
| 180 mm | 190 mm | 103% |
| 190 mm | 200 mm | 108% |
| 200 mm | 210 mm | 114% |
| 210 mm | 220 mm | 119% |
| 220 mm | 230 mm | 124% |
| 230 mm | 240 mm | 130% |
| 240 mm | 250 mm | 135% |
| 250 mm | 260 mm | 141% |
| 260 mm | 270 mm | 146% |
| 270 mm | 280 mm | 151% |
Important: Foot width also matters. After scaling the length, check the width in your slicer. You may need to scale X/Y slightly differently depending on the foot shape.
Disclaimer
This is a 3D printable slipper model, not a certified safety shoe or medical footwear product. The anti-slip sole pattern may improve grip, but it does not guarantee slip prevention on all surfaces.
Grip performance depends on the TPU type, print quality, layer adhesion, surface texture, floor material, dust, water, oil, and wear over time. Always test carefully before use, especially on smooth, wet, or slippery floors.
TPU flexibility varies by brand and hardness. The recommended 7% infill gives a softer feel, but users who need more strength or support should increase infill, wall count, or use a firmer TPU.
Resize the model before printing. The included model is 185 mm long at 100% scale, and the final fit may vary depending on foot shape, filament shrinkage, and slicer settings. Children should use the printed slippers under adult supervision.
