 I posted before that I was going to make some of these via rapid proto plastic. Here are picts of the Alpha unit:
It needs more work. Please comment if you would like to see a finshed product. I plan to tweak the dims and make a Beta unit soon. Edited: 21 July 2010, 9:46 p.m. ▼

that is one of the most useful replacement parts you could have made. a lot of those doors are lost. be sure to try your prototype in a few spice units. some doors will fit one calculator but not others. they had great keys but not very good casting (or whatever you call that process).

Yep, I agree with db, some of these doors are always made for the other calc... I have seen some of these broken, but it seems to me it is because of this very same fact: as they do not fit in, a bit of extra 'brute force' and they snap. Some of them are a bit loose sideways, and in this case they fit in almost every Spice. Something to check out... I cannot tell for sure, but I have been with a bunch of Spices and I saw at least three broken doors. I glued one of them and kept it in one of my Spices, 'just in case', and it is still in one piece. Of course, I do my job removing and replacing it carefully, so it does not count for a daily use. Great handcraft! In time: have you thought about the little Voyager´s battery door? They are smaller and a lot easier to disappear and/or crack. Well, because they are smaller they may also be harder to carve, but they have less details to be considered and they are much easier to place/remove, so they do not crack so easy. I think it would find some more interested people, too. About the color of the prototype:: you know what? I do not dislike it. My HP34C would look very distinctive with a white/beige battery door...
