(where PVA support material experimentation is in its
infancy). Also,
the injection-molded DEC toggle handles have their own molded pivot
pins (which do occasionally break off), which are so small that they
would not be strong enough with any 3D printing technique. There are
alternatives (like piano wire pivots), but it complicates the effort.
My experience of real DEC handles is that these pivots are the major
failure mode. If you have the old handle, you cna caefully drill out the
pivot and fit a metal rod (piano wire, etc) -- but make sure you have
everything correctly aligned before you drill!.
As regards (coming out of the woodwork, I'll happily agree I've never
used a 3D printer. But I have used plenty of frontpanel switches, and I
have had plenty of plastic compoentns fail. THat's why I was _asking_
how the strength of the 3D-printed one would compare with an original. I
don't know, please eductate me.
Loo, come up with the 3D design, print a set of them, fit them to your 8
or 11 and toggle in varios bootstraps, diagnostics, etc. Then yo ucan see
if they;kk hold up.
