Jeffers' Block

thingiverse

I recall spotting this spacer block for the first time when Dave Jeffers had just completed building it on his Bridgeport - all of that was done in roughly 15 minutes. Try as you might, good luck speeding up your print time to match that of a seasoned machinist's cut. Chances are slim that you'll come close. EDIT: Luckily, I took pictures back then, and upon reviewing them dated May 23rd, 2007, I'm planning an update to make the model more accurate by closely matching what was photographed.
