This is currently made out of 2 pieces of milled POM plastic, final version will be from anodized aluminium.
3D printing is not accurate and clean for me, tried that as proof of concept.
I trust milling much more. POM is suitable material for long term use compared to PLA what does not tolerate higher temp and being used to screw down etc.
But that’s where my way of looking it goes out of window in “DIY” and “Cheap” ways of thinking about it.
My design is neg carrier 2 parts + pipe to block frontal cap between lens and negative. I think this is only “turnkey” solution in the world for end customer. I’m aiming for customer who wants working solution, not DIY kit
But thinking about future…I think it would be possible to turn this into some kind of kit considering customer has their own camera + lens combo. But today I don’t want to make it “fit for all camera+lens” combo product as it would need to be so adjustable that it would look and feel ugly AF. So first I think it would make sense to produce kits for certain camera+lens combos, most likely Sony A7 series + macros between 50mm-70mm for example. But I don’t know if and for what price market would be interested for that.
