Disclaimer : I have designed and tested only one custom sintershell, which you can see
here.
I too really like the idea of making a re-usable container as component of a multi-part item. However, the cost of doing this is significant. Like- several times the cost of the items it's intended to contain.
What I ended up doing was making a disposable wrapper which just held the items, using as little plastic as I thought I could get away with, and maximising the aperture size (to reduce the increase in machine-space cost). This gave a reduction in cost of about 25% for 4 items, i.e. buy 4 for the price of 3.
Also, if you want the stuff polished and/or dyed, you need reasonable holes to let the polishing media/dye in.
So for moderate numbers of items, there really isn't much to play with before the cost outweighs the gain; I don't think 'nice' containers are economically feasible.
If you need to hold many very small items, this is much less of a problem, though.
If it were my own design, unless it was huge I'd put a hinge of some sort on one side and a single locking ring or bar through both sides on the other. Much less to cut through.
...Although I once saw a separate-the-bits puzzle which I believe was printed as a single part in 'locked' formation and went through the process fine - so theoretically, perhaps even no cuttin
Thanks for your reply. I like the sintershell you created, very clever!! Yes, so far I haven't been able to create one that would really be practical. I'll probably keep trying though.
