The file 'Codenames Duet Minimalist Insert 3D Printer Model' is (stl) file type, size is 26.8KB.
Codenames Duet compatible insert with less material cost, Around 80-90 grams only. It has holes for easy picking up cards.
Unlike other inserts, this one fits in only half of the original box and can be printed in one piece on printers such as the Ender 3.
My idea and suggestion is in the future to be able to use the other half of the box to store a card grid like the ones I have seen from other authors:
Codenames Card Grid by shannohakkinen. Not sure if fits entirely.
