What you will learn

• Using many Hole shapes at once
• Spheres as dents
• Putting half a shape inside a surface

Shapes you need

BoxSphere (hole) ×7

Steps

1. The cube

   Add a Box 30 × 30 × 30 at Z 15 (white).

2. Top face: five dots

   Add a Sphere 5 × 5 × 5, make it a Hole and place it at Z 30 (the top surface), so only half is inside. Duplicate it to X/Y: 0,0, −8,−8, 8,8, −8,8, 8,−8.

3. Front face: two dots

   On the front (Y −15) place two more sphere holes at X −7 and 7, Z 15.

4. Group everything

   Press Ctrl+A to select all, then Group. The dents appear.

5. Check

   Use Home and Top views. Export to STL.

Why it works

A hole centred on a surface cuts a half-round dent. Moving it deeper makes a deeper dent.
