Thank you Christopher,
(also on the information where i can find a set of plans), will get them as soon as i find some extra funds for modeling
well, progress is slow, test assembly showed some mistakes in the outline, second test is on its way, as soon as i solve technical difficulties with printer.
In the meantime, im working with bits and pieces whenever i have some spare time, here is the newest result, has bit less details than CMK's part, but thats only due the technical limitations, tiny bits and pieces can be added by scratching some of the fiddliest parts.
note, i didn't draw a series of cells, since this can be done in sub-assembly, and later on stacked simply together.
regards,
Marko
