Some kits also have the digital models available and others don't?

My Elden Ring and other more recent prop models I made specifically for my printed kits and are initially private/exclusive to me, for older models such as Dark Souls 3, Bloodborne, and Nier Automata etc I made those years ago before I had an FDM printer myself and have already been selling them for a long time which is why the models are also available. That being said I do intend to eventually have all digital models available as well, I just do not have a timeline for when I will do it, some I have already released publicly. I completely understand that someone with a printer wouldn't want to pay for a print when they can do it themselves or use more exotic materials (something I will eventually offer too when I have an enclosed printer), but my recent models weren't made for that person initially so please be patient.
