Ground spike for umbrella 21mm

Hi,
I’ve prepared a spike for a garden umbrella that can be driven into the ground. Mine broke, so I designed my own. Maybe someone else will find it useful.
I recommend printing it with ABS filament.

Dimensions:

• Shaft diameter: 21 mm
• Shaft height: 50 mm
• Total height: 107.2 mm
• Diameter for securing pin: 5 mm

After printing, the two halves should be glued together.
