Got around to measuring the pieces, and realized I did something extremely stupid. I forgot to take into account the fact that the parts will shrink upon cooling. Between that and what I am guessing is the print head not laying the material completely precisely, the piece is nearly 2% too small, which I cannot compensate for by boiling it in water. I did some sanding, which didn't really help.

I did learn that Alloy 910 is extremely soft after you put it in warm water, which worried me a little. I think I'm sticking to PETG as it is stiffer and much cheaper.

I am going to try a 110.5mm print which in theory should shrink to 109.1mm, but if it is anything like my experience this time, it should end up more like 108.7mm, which would expand to 109mm after I boil it for a bit.

At this point I am getting close to 70% of the cost of the MWR aluminum pulley...T_T The quest for that last 0.3hp is a lot more difficult than I thought, but at least I am getting some experience with 3d printed stuff, which should be useful for future car endeavors.

Anyone have a Celica GT-S or Matrix/Corolla XRS they want one of these for? Help me recoup my costs lol.
