Heart Jigsaw

I need a simple design of a heart in 2 versions
As a line drawing in PNG format, Medium quality.

A large heart with 9 random shaped interconnecting pieces - like a jigsaw
Option 1 with a central heart with interconnecting heart
Option 2 with random shapes throughout

Each piece must have at least 1 male and 1 female 'heart shaped interlock' within it's shape outline (See drawing)
Interlocking bottom of each heart must be a minimum of 2mm to be stable/strong
Each individual piece should be of roughly equal sizes of variation 70% > 100% of the below size
Each individual piece must not be larger than 75mm x 85mm (i.e fit with a square box of a slightly larger size (81mm x 91mm) See drawing

The overall pattern should also include/allow for a central large heart (30% of main size)
So..
1 Design with random shapes but with a Heart within the main Heart
1 Design with just random shapes

.....See drawing - Guide only


The central area that is greyed out must not have any connecting hearts - just the lines for me to overlay other images later

* Design will remain my copyright.
** I need the design in 2 options;
> 1 = as a Line drawing on white background
> 2 = As a black heart shape with the lines of each piece in white (A negative of the above)
in PNG format please

I need the initial design asap, ideally before the 1st of January 2024
I do not see much need for multiple revisions but would appreciate being given 1 week
to produce the stencil and then request any minor changes
