Overview
The Extrusion Foot protects floors from the sharp edges of 3030 aluminum extrusion and improves stand stability. Each foot:- Press-fits into the open ends of 3030 extrusion legs
- Provides a flat, wide contact patch for better grip
- Accepts adhesive non-slip pads on the bottom surface
You need 4 Extrusion Feet per stand assembly.
Compatibility
- Designed for 30 × 30 mm aluminum extrusion (“3030”) with open ends
- Works with the OSSM Extrusion Stand/Base
- Press-fit tolerances vary by printer and filament; minor sanding or shimming may be required

| Nozzle | 0.4 mm |
| Layer height | 0.20 mm (0.28 mm acceptable for speed) |
| Walls/Perimeters | 6 |
| Top/Bottom layers | 6 (≈ 1.2 mm) |
| Infill type | Gyroid or Cross Hatch |
| Infill percentage | 25% |
| Supports | None |
| Adhesion | None or 2–4 mm brim if corners lift |
| Orientation | Flat pad face down on the build plate |
Installation
Print and clean
Print four feet. Remove any stringing; lightly chamfer or deburr the press-fit edges if needed for a smooth insertion.
The foot should seat flush against the extrusion end and not rock.
Apply non-slip pads
Apply a 1.5” (38 mm) square non-slip furniture pad to the bottom of each foot.
Center the pad so it does not overhang; overhang can peel during lateral loads.
Press-fit into extrusion
Align the foot with the open end of the 3030 extrusion and press in by hand. Use a soft mallet if necessary—avoid striking the pad surface directly.
Troubleshooting
Foot pops out during use
Foot pops out during use
- Ensure a fully seated press-fit; remove and reinsert with firm pressure.
- Add a thin wrap of painter’s tape to the extrusion end to increase friction.
- For TPU prints, increase wall count or reprint in PETG/PLA+ for a stiffer interface.

- Replace worn pads or upgrade to higher-friction furniture pads.
- Clean both floor and pad with isopropyl alcohol to remove dust and oils.
- Consider TPU feet for added grip.

- Mix pad thicknesses or add a thin shim under the shortest foot.
- Verify all four feet are fully inserted and flush.
