Some time ago I needed to replace fans under mobo and PSU. To do it, I needed 50mm clearance, so I designed that Hefty Feet.

You can use it in 3 ways:

• just slide them in to profile
• bolt to profile with 3x m4 nuts and screws (min lenght 15mm)
• bolt down to surface with 5mm countersunk screws

I printed them with 10% gyroidal infill and pour resin inside with steel shavings filler.
