FluidMaster Flush 'N Sparkle Refill Cap

thingiverse

Don't discard those FluidMaster Flush 'n Sparkle cartridges and save money by adding this simple removable cap (and liner) that you can print easily, reducing plastic waste sent to landfills. The refill tablets fit perfectly like the originals, with just a careful pull-out of the OEM cap and a twist-on replacement with the 3D printed slotted liner. Once refilled, use them right away or store replacements in zip-lock bags until needed. To ensure durability, print with chlorine-resistant plastics such as PETG or ABS, not PLA. Cura proved to be an excellent tool for creating supports within the adapter ring, allowing precise printing of the necessary slots. Other slicer programs can sometimes generate too many unnecessary support structures, wasting resources and reducing efficiency.
