I designed this as a useful standard 3D Printer test model. Test printer settings, various filaments, support settings etc. Forget Benchy models that only go in the bin. These can be used in around your home even if they don’t turn out perfectly. It prints in place, thus testing the hinges and articulation after removal from the print bed. It proved interesting to see the variable results from the same brand of filament but in different colours. I tested pretty well all of my PLA filaments, Bambu, Sunlu, Anycubic, Tinmorry, Monoprice, Amazon etc, to understand their pros and cons with sizing, strength of layer bonding, ease of support removal, etc.
