Hello,
just send what you need by registered mail to my office in Budapest.
But:
A) my oven can not handle large pieces
B) I am semi-retired. So things can take time, as I have so many jobs...
With best regards

Harvey,
try to "temper" the PLA. Use a reflow oven.
I can try that. Right now, I'm working on making a board positioner
for the binocular microscope that reads positions of parts from the
board file.
I don't have any cases that need work until I start to make cases for
stuff myself.
I have heard of smoothing the PLA by putting it in acetone vapors for
a bit. That always sounded rather dangerous to me, and then again,
how long to leave it in is another matter. Hmmm, acetone vapors in a
glass jar....
I may forego that experiment.
I'll wait and see what I need, and thanks for the offer.
Harvey
If you want, you can send me some samples to HU and I will use my
"Wassulmayer" oven.

I don't know. I'm fairly sure the OEM part was plastic. The parts don't seem to be under much stress, and the stress is distributed along the length. I've never done 3D printing, but a few components I've encountered that are printed seem to be made of material that would be strong enough. There doesn't seem to be any other practical way to keep the cabinet halves together, so I'm pursuing duplication of the zippers. Any other idea would be appreciated!
3D printer materials vary widely in strength.
PLA is pretty generic, ABS is available, some other varieties are
available as well as flexible filament.
You'd need a heated bed printer for some of them, though.
I'd be tempted to try a good ol' cheap print out of PLA to get the
sizes right, then see how that works.
Infill, wall size, and layer thickness also change strength of the
part as well.
PLA is cheap, but not very rugged, and definitely not as heat
resistant as you'd like, perhaps.
