Disposer Splash Guard

thingiverse

It's often simpler to craft and assemble a replacement part than to search for one to buy. My old disposer splash guard, also known as sink baffle or rubber cover, needed to be redesigned. This required a strong flexible material like Ninja SemiFlex (TPE). My disposer has an opening of 77mm and shoulder diameter of 85mm, making this part the perfect fit.

After printing, the usual trimming + hole punching + slit cutting is required. The part needs axial slits to create a flexible aperture. I cut four slits, each extending to holes punched about halfway up. To make it larger, you can cut higher and punch more holes. I used a circular sweep object for design. The collar opening and shoulder clearances are measured along with the noticeable taper that dictated the rim bead design. The height of the rim bead was guesstimated at 5mm for adequate strength. The 60-degree rise is super easy for FDM printing. The thickness of 1mm eliminates Z-hop of the printer head, allowing for a continuous bead after the rim is printed.
