I see what you mean. We all expected to receive source files for free when come to 3D printing. I give my salutes to people out there who are willing to give away the source files for free.
From my point of view, I've spent the time to design the case and pcb as I would have on a case made of other materials. Imagine asking for the source file of an aluminium case because CNC service is now readily accessible.
Another reason for not releasing the source file is that I'll able to ensure the quality of the products that carry the brand name.
I made it clear this is a keyboard in a 3D printed housing and I think the price reflects that. This is not for everyone for sure, but I hope someone out there is interested in this kind of products.
Oh I totally get that. I do a ton of work like this as well, and I totally understand getting paid for the time and effort you put in.
My main concern isn't that the case is closed source (though I do prefer open source), but that 3D printing isn't as durable/high quality as other materials. Case's will be easier to damage/won't last as long. If the files were open source then users could just print a new case as needed. But given that its not, someone would need to create an entirely new file set for it when there's needs to be replaced. When I'm investing in a keyboard I really want it to be something that will last me for years and years to come. 3D printing is great for prototypes, just not a fan at all for long term investments.
I wouldn't want people to think this keyboard is an investment as such. I want to position this board as an entry board with many features crammed in. In this case(!), the features are split, RGB, OLED, encoder and possibly audio. This gives opportunity to try many things out with a single board, and with the familiar QWERTY layout, it will still be welcoming to use after playing with it, compare to other ortho board with similar features.
I understand 3D print PLA is not the strongest material, but It will still last a long time if being careful with it. The same goes for many things, for example, PCB can be fragile if not handled properly, components can be knocked off or solder pads could come off if not using solder iron properly. IMO, I don't think it is the reason to justifies to open source. Nothing last forever after all.
PCB only option will be available if someone wants to make the case themself. I'm also considering offer case only option for those who have concern about the longevity of the material.
