Big word incoming!
I started the reprint last night with PLA supports and the print failed pretty quickly - I'm fairly certain my PETG was dampish. I replaced the silica in the AMS and let it sit overnight.
Big word? I had an epiphany last night! This stupid thing is a 4 hour print and it keeps failing towards the top (except this last one that was a fluke). It uses a TON of support to support the top of the clip for the pump. Epiphany? I flipped it on the side. Now it has a small row of thin supports under the hanger and two for the clip. 4 hours reduced to 1.5 hours AND it eliminates the "tall print wiggle" factor. I'll be printing it here around 6.
The other nice thing about printing it this way is instead of the layers holding the weight so if any single layer fails the whole print fails - now each layer is vertical when hanging so instead of each layer having to be fused properly for strength, each layer can independently hold the weight of the gyre! Built in strength and endurance.
Next: redesign the IceCap 2K vertical hanger and reprint it!
