The lens cap thing has got me thinking about 3D printing again. I need lens caps and camera body caps quite often, and getting the weirder ones is difficult, slow, and sometimes expensive - for example, I've needed Exakta caps a few times and they are expensive, but you can get them as 3D printer files. And I might conceivably want to amuse myself by undercutting matey with his £5.49 lens caps...
And sometimes it would be nice to adapt a lens to take a few test shots on one of my cameras, but I don't want to go to the expense of buying a commercially made metal mount - I've bodged this a couple of time in the past by e.g. gluing a rear lens cap to a body cap and drilling a hole through the plastic to let the light through, but it's a total pain to get right.
I really don't want to keep asking my friends for favours on this, so what I'm wondering is what's around in the way of affordable 3D printers that can do this sort of thing but won't break the bank. The maximum sized thing I'd want to print would be say 60mm diameter and a centimeter or two high (but bigger might be useful for other projects). Reasonably good precision is important with adapters since the whole point is to make a fairly precise connection between things that were never designed to joint together. A good opaque black material is more or less essential for the filament when printing lens adapters, anything else will probably leak light, but a range of colours might be nice for other things.
So.... what's available at a reasonable price, and how idiot-proof is it?
