Well aside from me printing too hot, I got one decent corner printed in 19 hours. but it’s square. I pulled out 50mm from each direction and then measured between each and got no deflection whatsoever. perfect 90 on the first try. I’m gonna go back to the printrbot for the next run, which should speed up per part time and give me a better print overall. I think it might be a good idea to also reprint the spacer at 100 percent infill to reduce the chance of it getting squashed and shrinking overtime. maybe even upscale the spacer and print it in semi-flex.
