Christmas Tree Base (Hexagon) with SCAD

My small Christmas tree base broke, so decided to look up a new one on Thingiverse. The only one I found was an Octagonal version, which did not fit my needs. Luckily it came with an SCAD file for modifying.

Here is the Hexagonal version fitted for my tree (sizing below), you may want to use the SCAD to customize the sizing for your specific tree:

inner_radius=3.90;
outer_radius = 18.5;
wall_width = 2.5;
slot_width = 2;
part_height = 43;
