The 12lb DUMMY is simple assembly used in the NHRL Functionality Test for 12lb weight class. The DUMMY will be reviewed and may be tweaked in upcoming events.
The assembly is made up of the following components:
| Component | Source | Number Needed | Weight Per Item (g) | Total Weight | Material | Infill Setting |
|---|---|---|---|---|---|---|
| Lower Weight Holder | 3D Printed | 1 | 117 | 117 | Bambu Labs PLA Basic | 15% Grid Infill |
| Upper Weight Holder | 3D Printed | 1 | 71.4 | 71.4 | Bambu Labs PLA Basic | 15% Grid Infill |
| Short Wall | 3D Printed | 2 | 64.4 | 128.8 | Bambu Labs PLA Basic | 95% Grid Infill |
| Long Wall | 3D Printed | 2 | 68.2 | 136.4 | Bambu Labs PLA Basic | 95% Grid Infill |
| Lid | 3D Printed | 2 | 184.5 | 369 | Bambu Labs PLA Basic | 95% Grid Infill |
| Inner Spacer | 3D Printed | 5 | 1 | 5 | Bambu Labs PLA Basic | 15% Grid Infill |
| Foot Spacer | 3D Printed | 4 | 2.2 | 8.8 | Bambu Labs PLA Basic | 15% Grid Infill |
| Rubber Bumper | McMaster | 4 | 5.8 | 23.2 | ||
| Bolt: 1/4-20 x 3.5 | McMaster | 4 | 22.8 | 91.2 | ||
| Bolt: 1/4-20 x 3 | McMaster | 1 | 19.5 | 19.5 | ||
| Nut: 1/4-20 | McMaster | 5 | 2.5 | 12.5 | ||
| Weight | Amazon | 2 | 2268 | 4568 | Cast Iron |
All 3D prints use the following settings:
3 Floor Layers, 5 Roof Layers, 2 Wall Layers.
Total Weight: 5551g ~= 12.2 pounds
For those who would prefer to cut their own weights, they can be easily cut from steel plate. A small spacer may be needed to account for the difference between the width of the commercially available weights versus the laser cut steel.
