Do you have a Waterpik Traveler Water Flosser and find that it REALLY needs a lid? That's what we found after even our son complained that it was kind of gross that the water just sat there uncovered for what could be days on end.

Well, no more: "John, can you please just make a lid for this?" Yes, yes I can!

Introducing THE LID for Waterpik Traveler Water Flosser (WP-300) (otherwise known as the Kid's Waterpik). The 3D-printed lid for this Waterpik is a durable and functional accessory for the popular portable flosser. It just fits right over the top of the water tank and keeps it free from splashes, dust, bugs, and other stuff you don't want to get into the water tank when not in use. It doesn't fit tightly so that kids can easily remove it and put it back on after refilling the tank - rather it just sits on top.

This cover for the Waterpik tank is 3D-printed in earth-friendly and durable PLA plastic with a nice texture to it. It's available in multiple colors, although we recommend white!

This is a 3D-printed, plastic item. Due to variables inherent in the printing process, it may have blemishes, layer lines, and other defects and/or minor sharp, small pieces of plastic which can be harmful if not handled properly. Sharp/rough edges can typically be smoothed with a heat gun or hair dryer, lightly softening the plastic then smoothing with a finger or other object.

That said, we work very hard to ensure that each item has a certain standard of quality. Please let us know if something is not up to snuff and we'll do our best to fix it!


We use durable PLA plastic for most of our items. Learn more about PLA here.

For automotive and other products that needs heat-resistance, we use PETG plastic.
