Sand Screw for Beach umbrella - 25mm Shaft

Updated to v3, earlier versions had some mistakes in them.

This is the sand screw. Designed for the beach umbrella with 25 mm diameter shaft.

Supplies for 25 mm:

2 M4x30 screws 1 M3x40 screw 2 M4 locking nuts 1 M3 locking nut 3D printer with rigid, e.g. PETG plastic

I recommend the following settings for max strength:

0.3 layer height
Wall Line Count = 6
Top & Bottom layers = 6
Nozzel Temp = 235c
Supports = Normal & Touching Buildplate

Ignore any "not water-tight" errors from Cura, it'll print just fine.
