30mm Square Tube Clamp-on Bracket
Print Profile(1)
Description
This is a 3D Printed clamp-on bracket for 30mm square tube/steel pipe racks
I currently printed two, which clip directly onto the rack to support subwoofers, small speakers, equipment boxes, or other light to medium weight items
The bracket features a clip-on structure + diagonal reinforcing rib design, requiring no drilling or screws, and can be used by simply hanging it on a 30mm square tube. The overall structure is quite sturdy, making it suitable for use with desk racks, shelving units, metal racks, audio racks, and similar setups
Model Dimensions
| Item | Dimension |
|---|---|
| Overall Length | 180 mm |
| Width | 30 mm |
| Thickness/Height | 40 mm |
| Compatible Tubing | Approx 30 mm thick/side length square tube |
| Recommended Quantity for Use | 2 pieces used as a set |
Suitable for clipping onto 30mm square tubes. If your square tube has paint, rubber coating, or dimensional errors, it is recommended to first confirm the actual thickness, and if necessary, fine-tune the scaling in slicing software
Main Uses
Can be used for:
| Use Case | Description |
|---|---|
| Subwoofer bracket | Two brackets used as a set, clipped onto the rack to support a subwoofer |
| Small speaker bracket | Suitable for desktop speakers, satellite speakers, etc |
| Equipment tray | Can hold routers, power supply boxes, small amplifiers, etc |
| Rack extension support arm | Adds a temporary support position to metal racks, square tube racks |
Design Features
- Compatible with 30mm square tubes: Suitable for common metal racks, desk racks, and shelving unit square tubes
- Drill-free installation: Can be used by simply clipping onto the square tube
- Thickened structure: Overall 40mm thickness for enhanced stability
- Long support arm design: 180mm length, suitable for supporting subwoofers or deeper equipment
- Diagonal reinforcing ribs: Enhance support stability and reduce deformation under stress
- More stable when used in pairs: Recommended one on each side for more even weight distribution
Printing Recommendations
| Setting | Recommended Value |
|---|---|
| Material | PETG / ABS / ASA preferred, PLA also usable for light indoor loads |
| nozzle | 0.4 mm |
| Layer height | 0.2 mm |
| Wall thickness/number of walls | 4–6 walls |
| Top/bottom layers | 5 layers or more |
| Infill density | 30%–50% |
| Infill pattern | Gyroid / Cubic / Grid |
| Support | Depends on print orientation |
| Recommended print quantity | 2 pieces |
If used for vibrating equipment like subwoofers, it is recommended to use PETG, ABS, or ASA. Long-term weight bearing with PLA is not advised, especially in high-temperature environments or direct sunlight during summer
Installation Method
- Print two brackets
- Clip the brackets onto the 30mm square tube rack
- Adjust the distance between the two brackets so the subwoofer's bottom receives even pressure
- Place the subwoofer or equipment on top
- It is recommended to place a non-slip pad, rubber pad, or sponge pad on top of the brackets to reduce vibration and sliding
Usage Notes
- Before use, please confirm if the square tube size is close to 30mm. If there is looseness during installation, a suitable layer of sponge pad can be applied
- Subwoofers vibrate, so adding non-slip pads is recommended
- It is recommended to use two or more brackets together; a single bracket is not recommended for sole weight bearing
- Weight-bearing capacity depends on printing material, print orientation, infill density, and layer adhesion strength
- It is recommended to perform a weight-bearing test before using heavy objects
- Not recommended for human weight bearing, hoisting, or high-risk scenarios
