with FLEX filament you can really print 4D - so your 3D-prints folds into a final structure. The fingerloop, where the cap is also attached to, has at its end a small ball to stick in the hole at bottom.
Nope, still just 3D
@pave_spectre are you sure, as you maybe only can perceive 3D-Objects?
Just for the sake of discussion… I’ve been thinking that all 3D printing is actually “4D” printing because it needs the 4th dimension of time for anything to be created.
