Rectangular calibration block with four holes |
Create a centered 100 x 60 x 20 mm block with four 8 mm vertical through-holes. Add only a 2 mm chamfer on the top outer perimeter. |
 |
| 2 |
Circular flange with bolt-hole pattern |
Create an 80 mm diameter, 10 mm thick circular flange with a 30 mm central through-bore. Add six 6 mm through-holes on a 60 mm bolt circle and fillet the outside circular edges. |

| 3 |
L-bracket with gussets and two hole directions |
Create an L-bracket from a base plate and rear vertical plate. Add vertical base holes, horizontal back-plate holes, two triangular gussets, and a filleted base/back transition. |
 |
| 4 |
Stepped shaft with keyway |
Create a 120 mm shaft along X with 20/30/20 mm diameter stepped sections. Add end chamfers and a shallow rectangular keyway on top of the middle section. |

| 7 |
Radial-engine-style cylinder with cooling fins |
Create a vertical engine-cylinder form with a central barrel, 12 cooling fins, a base flange, and a top cap. Add a 35 degree angled spark-plug boss with a coaxial through-hole. |
 |
| 8 |
Centrifugal impeller with backward-curved blades |
Create a centrifugal impeller with a backplate, hub, and through-bore. Add 12 fused backward-curved blades sweeping about 45 degrees from root to tip. |
