What's with the odd sizes on the threaded/smooth rods in the BOM for the Prusa? ie: M8×294mm front / rear 8mm×406mm Y-bar why not 295 or even just 300mm for the front/rear and 405mm for the ybar. which brings me to another question: Could the overall size be tweeked so we can get most the rods the same size and make it a little bit more simple?

yeah if we're cleaver we can tweek the mesurements to get the most out of the most comonly sold lengths of rod (1m I think?)
if we're extra clever and keep the triangle proportions the same, we won't have to adust the printed parts.]]> se5a General Fri, 14 Oct 2011 21:23:55 -0400 https://reprap.org/forum/read.php?1,101406,101418#msg-101418 https://reprap.org/forum/read.php?1,101406,101418#msg-101418 NelsonRap General Fri, 14 Oct 2011 21:01:15 -0400 https://reprap.org/forum/read.php?1,101406,101413#msg-101413 https://reprap.org/forum/read.php?1,101406,101413#msg-101413 Sublime General Fri, 14 Oct 2011 20:09:06 -0400 https://reprap.org/forum/read.php?1,101406,101406#msg-101406 https://reprap.org/forum/read.php?1,101406,101406#msg-101406
ie:
M8×294mm front / rear

8mm×406mm Y-bar

why not 295 or even just 300mm for the front/rear
and 405mm for the ybar.

which brings me to another question:
Could the overall size be tweeked so we can get most the rods the same size and make it a little bit more simple?
