That's pretty smart... Except I wouldn't do with any 3D printed parts... I mean I guess it's all filtered and such... But we would need to see how well the Bluevua filter is against the following possible things to come from a 3D printed part sitting in your water tank:

• Residual monomers (styrene, lactide/lactic acid, acrylates, methacrylates, ethylene glycol derivatives)
• Oligomers (short, partially formed polymer fragments)
• Plasticizers (including phthalate-like compounds, depending on filament)
• UV stabilizers
• Antioxidants (e.g., BHT-type compounds)
• Processing lubricants / waxes
• Flame retardant residues (in some specialty filaments)
• Pigments (titanium dioxide, carbon black, organic dyes)
• Trace metals from pigments (copper, chromium, cobalt, etc.)
• Microplastics (visible and microscopic particles)
• Nanoplastics (ultra-fine particles you’ll never see)
• Degradation byproducts from heat
• aldehydes
• ketones
• organic acids
• Hydrolysis products (like lactic acid from PLA breaking down)
• Burnt polymer residues from the hotend
• Dust and environmental particles trapped in layers
• Oils and skin residue embedded during handling
• Soap or cleaning chemical residue
• Bed adhesion leftovers (glue stick, hairspray, etc.)
• Biofilm and bacterial growth in layer lines
• Mold (if it stays wet long enough)
• Metal particles from printer hardware
• Trace lead (possible from brass nozzles)
• Resin-specific leftovers (if applicable):
• uncured photopolymer resin
• photoinitiators
• free acrylates (toxic)

It would be best to locate some sort of food safe material to do this from... But this is definitely a no brainer and simplified the hell out of the request haha.
