got up this morning and took a look at the pour i did last night, and all four came out great. nice and solid, completely covered, and ready for clean up. so will move forward using the same process, 2x2 set up four molds, mix & pour 2, mix and pour 2, then let sit for 4+ hours, then remove and let cure for 48+ hours. figure can do 4 sets a day if i have the time. 

molds opened up, black urethane on black PLA is kinda hard to see, but look at the funnel area

all four seals removed

batch 3 done and done

molds opened up

seals removed

Batch four has been poured, and will cure overnight, then remove that batch

prep and pour batch 5 in the morning if all goes well... only 2 more batches to pour and then out of materials... mainly metal insets !! should have enough urethane to complete all sets with a tad to spare.

Friday morning update....

have 6 1/2 sets complete, should be able to make another 3 1/2  sets to get me 10 total sets.

I have randomly takes 1 seal here or there and torn them apart and validated cure at various stages, 6 hours, 12 hours, 24 hours, 48 hours look at how it is curing, adhering to the metal inset, etc...  looking good so far. up until 48+ hours they are still gooey in the middle. and the longer it sits the stickier it gets. but after 48 hours they look good, solid. the metal inset provides a nice backbone to support and hold the shape. with no inset i can fold the urethane on itself and not tear or rip. do not recommend trying, but i did it as a test. with a metal inset it will hold the shape you bend it to until the metal fatigues. the chamfer works for slotted flat head screws. since the seal is universal and flips for left or right.

once i get them all past 3 days cure i will trim them up and then cut the slit based on the scribe.
