[rescue] Sparcserver 1000 board eject levers!

[Steve Hatle]

I tried to send this before, but I'm guessing it got eaten because of 
included links(?) I'll try again - you can contact me directly for the 
necessary links to the levers and the compression pins.

Greetings all,

After my plea for a source for an STL file for board eject levers for 
the Sparcserver 1000/E, list member Dan Moisa stepped up and modeled an 
original ejector, and I can report it works great!

He is willing to share, and so you can get the file from his GitHub. 
Contact me for the link.

I printed the levers on my Prusa with PLA at .15 layer height and 30% 
infill, and they seem plenty strong.

As far as the pins, I ordered some 2.5mm by 6mm compression pins online 
which seem to be a direct replacement for the original part. Contact me 
for the link.

I did find that the fit was a little too tight for the hole in the 
lever. Dan offered to widen it out a bit, but instead I used a 7/64 
drill bit to chase out the hole and then the pins fit in snugly without 
excessive pressure. A 2.5mm bit (if you have metric sizes) should do the 
job as well.

These pins took a while to arrive from overseas; I'm guessing just about 
anything that's 2.5mm in diameter will work, as long as they don't hang 
down past the bottom of the board as it's inserted. There more room on 
the top.

I'm sure there may be better material than PLA to use to print these, 
but that's what I had handy, and as I said it seems to be strong enough. 
Will it last for another 30 years? Probably not, but I don't plan to be 
pulling the boards in and out of my SS1000 that much, and it looks way 
better than the janky zip-tie pulls I had made before.

Thank you _very_ much to Dan for doing the work to model the lever, 
making an adjustment to better fit the board width, and especially for 
being willing to share the STL freely to the community! I plan to put 
the STL up on Thingiverse/Printables as well and try to get the news out 
to the community at large.

If you want to see pictures, message me off-list and I can send some to you.
