Made with ABS on a Replicator 2X. Had to scale it to 101% to compensate for the ABS's shrinkage. The one on the far left was too big at 102%. The all-white stub was at 100% and was too small. The third one was at 101% but failed because I was trying on-the-fly filament swapping. I failed. And lastly, the 4th one was a success, even with on-the-fly filament swapping. At 101%, it fits well, but there's still a little wiggle room. Maybe next, I'll try 100.5%?
