Protect your surfaces from water damage with these customizable TPU drainage plugs, designed to seal drainage holes in planters brought indoors. Perfect for planters placed on tabletops or wooden floors, these 3D printable plugs prevent leaks that could stain or warp surfaces. Each plug fits holes from 12 mm to 20 mm, and the customizer lets you adjust the diameter, depth, and thickness for a precise fit. Ideal for controlled indoor watering, these plugs are a practical solution for maintaining your plants indoors. Note: For indoor use only; not recommended for outdoor planters in rainy areas. Be sure to check for a secure fit after you water the plant for the first time with the plug.

If you don't see the right size for your planter, select [CUSTOMIZE] to create one to fits it exactly. You probably only need to customize the diameter of the hole. The default hole depth and wall thickness values should work with just about any planter.
