Hi SheldonE,
I hope you don't mind, but I've changed the wikipage back to M10. Both the EiNSTeiN and the "official" Prusa versions use M10 for the long threaded rods now and having the wiki mention M8 might add to the ever growing confusion surrounding all the i3 variations
. If you happen to have y-corners that take M8, you might have printed parts from a much older revision of either version.

As far as I know, my parts came from the github repository linked on the main i3 page here. The Y-axis corners definitely have 8mm holes.

Both the single_plate and box_frame y-corners from Josef's repo use the M8/M10 combination now and already have for some time. But somehow people keep churning out parts from older revisions that still use the M8 holes for the longer threaded rods, leaving quite a number of people confused after having bought parts from Ebay
As a side note, the box_frame parts can be used for single frame builds too now, provided you set i_am_box to 0 in the config. As this seems to be the only version that sees active development, perhaps the original single plate parts could be considered depricated, even though those remain perfectly usable of course. Or maybe they're just "done"

I've heard of people doing so, but depending on the frame that you're using you might run into clearance issues. When you're drilling to 10mm exactly centred on the 8mm hole, the bottom of the M10 threaded rod will be 1mm closer to the surface the printer is sitting on. In case of a box frame that probably will result in the y-corners getting lifted from whatever surface your printer is sitting on. Ideally you want to keep the bottom of the hole at the same level. See my beautiful artist's impression of what I mean attached

Just in case anyone hits the same hurdle, drilling the hole out to 10mm works, but go very slowly. I drilled one a bit to fast and it cracked (delaminated):
I'm hoping it'll hold out until I can print off some new feet. Here's my Y-frame:

Yeah, haven't gotten that far yet, I'm still collecting parts, but it'll probably be MDF. I can't really afford to buy them all the parts at once. I'll be getting the last of my vitamins next pay and I'll start on the box the pay after.

Yeah, I watched you're video blog and noticed you skipped a few steps in the middle somewhere.

We don't have Bix Box in Australia and our local hardware stores (Bunnings) will only do one or 2 cuts for free.

Yep, corner squares are on the list of things to buy for the box. I already have 2 squares.

Yeah, I think it'll be a good old fashioned hand saw and some dead reckoning. *shudder*

Yep

Yep, thanks for the advice.
