@kirk Yes, that is the pump.
I should add a disclaimer that I still consider it early tests but if anyone wants to try some of these builds alongside me, I'm happy to share notes! Although it works, the sizing of the cavity for the tubing isn't quite ideal. The tube tends to twist. So I have a bit of refinement on either tubing choice or modifying the build files. Or trying other existing setups out there.
Thanks for the other notes! I continue, just slowly.
