Magnetic Pincushion.
Model is 4 parts:
Inlay (heart shape with 2 hollowed out spaces for the pins)
Bottom and Lid (parts are the same!)
Spacer (to keep the inlay and bottom aligned)
Add 2 magnets (I used 2 magnets of 2mm thick).
Glue them roughly on the 2 places indicated with the marking lines on the bottom of the inlay. Glue the spacer at the point of the heart on the bottom of the inlay. Now glue this in the bottom part.
When using thicker magnets:
Scale the spacer in Z to same thickness as used magnets.
For gap-less connection between bottom and lid with magents thicker then 4mm: you can scale bottom part in Z.
