Portal Companion Cube container & lid

Constructed this Companion Cube box from scratch after not being able to find exactly the design I was after. Created as a single mesh body in order to allow PrusaSlicer to properly interlink adjacent sections of different colours. Both plain STL and 3-colour 3MF provided.

Added a lid that has a raised and revised profile around the heart deboss to make it easier to grasp.

Internal dimension is provided as 65mm, but the photo is of one that I scaled up in PrusaSlicer to 90mm internal.

Printed on my Prusa 5XL with Polymaker PolyLite PETG (white, silver, pink) and standard 0.20mm structural settings (plus ironing on the very top layer.)
